Dealing with Difficult Instructors: A UK Gym Owner's Guide
Every gym owner eventually faces instructor challenges: consistent lateness, declining teaching quality, negative attitude, or outright conflict. These situations are uncomfortable but inevitable. Handled poorly, they destroy morale, drive away members, and create legal liability. Handled professionally, they either resolve the issue or end the relationship cleanly. This guide provides frameworks for addressing common instructor problems in UK gyms, navigating difficult conversations, following UK employment law requirements, and knowing when to part ways. Whether dealing with minor performance issues or serious misconduct, you'll learn how to protect your gym whilst treating instructors fairly.

Common Instructor Problems and Warning Signs
Instructor challenges fall into predictable categories. Early recognition allows earlier intervention when issues are still manageable.
Performance Issues: Poor Teaching Quality
Signs include declining class quality (members stop attending specific instructor's classes, complaints about unclear instruction or lack of structure, instructor seems unprepared or improvising randomly), safety concerns (failing to supervise sparring appropriately, allowing dangerous situations to develop, not enforcing tap respect or hygiene standards), lack of engagement (going through motions without enthusiasm, minimal interaction with students, checking phone during class, leaving immediately after class without member interaction), and technical errors (teaching incorrect techniques, unable to answer technical questions, showing techniques outside their expertise level, contradicting gym curriculum).
These issues often stem from lack of training, burnout, personal problems affecting focus, or genuine skill mismatch. Before concluding someone is a poor instructor, assess whether they've received adequate training and support. See our instructor training guide.
Reliability Problems: Lateness and Absences
Warning signs include consistent lateness (arriving at class start time rather than 15 minutes before, rushing setup without proper preparation, pattern of lateness even if only 5-10 minutes), frequent absences (calling in sick more than average, last-minute cancellations forcing scrambling for coverage, vague or inconsistent explanations for absences), poor communication (not responding to messages within reasonable timeframe, ignoring schedule change requests, failing to arrange coverage when unavailable), and pattern development (occasional issue becoming regular occurrence, excuses becoming less believable, defensive when questioned).
Reliability issues destroy trust and burden other instructors who must cover. Members notice and lose confidence. One Manchester gym lost 8 members after their Monday instructor was consistently late or absent for three months without consequence.
Attitude Issues: Negativity and Resistance
Manifestations include negative commentary (complaining about gym policies, members, other instructors to anyone who'll listen, nothing is ever good enough), resistance to feedback (defensive when receiving constructive criticism, argues rather than listens, dismisses suggestions for improvement), undermining leadership (contradicting your decisions to members, encouraging dissent, 'forgetting' to implement policy changes), affecting team morale (other instructors become negative or disengaged, toxic atmosphere developing, complainers attracting other complainers), and public criticism (posting complaints on social media, discussing gym issues in public BJJ groups, damaging reputation intentionally or carelessly).
Negative attitudes are contagious and corrosive. One toxic instructor can poison an entire team and drive away members who sense the atmosphere. Address attitude issues faster than skill issues - skills can improve, but someone actively undermining your gym rarely changes.
Boundary Issues: Inappropriate Behaviour
Red flags include inappropriate relationships (romantic or sexual involvement with students, particularly with power imbalance, inappropriate flirting or comments), physical boundary violations (unnecessary physical contact beyond instruction, touching students inappropriately under guise of technique adjustment), verbal inappropriateness (sexual jokes or comments making members uncomfortable, inappropriate discussions of personal matters, sharing members' confidential information), favouritism (obviously preferring certain members, giving special treatment based on attraction or friendship, ignoring or excluding other members), and online boundary issues (inappropriate social media interactions with members, direct messages crossing professional boundaries, posting photos of members without consent).
Boundary violations create serious liability and destroy trust. Zero tolerance is appropriate. Even if behaviour doesn't rise to illegal level, it damages your gym's reputation and creates hostile environment. Investigate immediately, document thoroughly, and act decisively.
Conflict: With You, Other Instructors, or Members
Indicators include conflict with gym owner (disagreement about fundamental direction, refusal to follow reasonable instructions, personality clashes affecting working relationship, tension visible to others), conflict with other instructors (arguing over teaching approaches or curriculum, competition for prime time slots or favourite students, inability to work together professionally, members sensing division), conflict with members (regularly butting heads with specific members, accusations of unfair treatment, complaints from multiple members about instructor's behaviour, creating us-vs-them dynamics), and unresolved grievances (instructor feels wronged and won't let it go, bringing up past issues repeatedly, seeking allies in dispute, poisoning relationships across gym).
Not all conflict is the instructor's fault - sometimes you're the problem, or there's legitimate grievance requiring resolution. Before labelling someone difficult, honestly assess whether they have valid concerns you're dismissing.
Loyalty Issues: Competing Interests
Signs include teaching at competitor gyms (particularly without disclosure, teaching techniques identical to yours, recruiting your members to other gyms), planning to open own gym (asking detailed business questions, copying systems and curriculum, recruiting members or instructors away), divided loyalty (prioritising other gym over yours, unavailable when you need them for competitor commitments, half-hearted teaching because saving energy for elsewhere), and intellectual property concerns (copying your curriculum for use elsewhere, sharing your proprietary teaching materials, using your brand and reputation to build competing operation).
Some gym owners prohibit instructors from teaching elsewhere through non-compete clauses. Others accept instructors work multiple gyms. Be clear on expectations upfront. If someone's building competing operation whilst employed by you, that's different from simply teaching elsewhere.
Prevention: Stopping Problems Before They Start
Most instructor problems are preventable through clear expectations and good management. An ounce of prevention saves pounds of cure.
Clear expectations from day one through written contract specifying responsibilities, compensation, schedule, expectations, instructor manual documenting policies, professional standards, procedures, induction session reviewing expectations and answering questions, and documented performance standards (what punctuality means, teaching quality expectations, professional conduct requirements).
Regular feedback - not just when problems arise through informal positive feedback regularly (recognising good teaching, thanking for effort, acknowledging contributions), scheduled check-ins (weekly for new instructors, monthly for established, discussing how things are going, addressing small concerns before they grow), formal performance reviews (every 6-12 months, structured discussion of strengths and development areas, goal setting and support planning), and creating culture where feedback flows both ways (you want to hear concerns early, open-door policy for questions and issues, don't punish people for raising problems).
Early intervention is critical. Small issues addressed immediately rarely become big issues. Lateness mentioned the first time prevents pattern developing. The instructor who's late once and receives gentle reminder 'I noticed you arrived right at class time today. Remember we need everyone here 15 minutes before for setup. Can you manage that?' usually self-corrects. The instructor who's late repeatedly without comment assumes it's acceptable.
Open communication culture where instructors feel heard, concerns raised and addressed promptly, transparency about gym performance and challenges, and involvement in decisions where appropriate. Instructors who feel valued and included are less likely to become problematic. Those who feel ignored or taken for granted often act out.
Having Difficult Conversations Professionally
Most gym owners avoid difficult conversations too long, letting problems fester. When finally addressed, the conversation is often emotional and reactive rather than professional and constructive. The structure below makes difficult conversations manageable.
When to Have the Conversation
Have difficult conversations early, not late (first or second occurrence of problem, not after it's become entrenched pattern, whilst relationship still salvageable, before resentment builds on both sides), and when you're calm and prepared (not in heat of moment after incident, not when angry or emotional, after you've prepared properly with facts and examples, when you can be professional rather than reactive).
Delaying difficult conversations doesn't make them easier - it makes them harder. The conversation after 6 months of lateness is far more difficult than the conversation after the second late arrival.
Preparation: Do Your Homework
Prepare thoroughly before the conversation: document specific facts and examples (dates, times, specific incidents, member complaints or feedback, pattern of behaviour not isolated incident), identify desired outcome (what needs to change specifically, timeline for improvement, support you'll provide, consequences if no improvement), plan what you'll say (opening statement explaining issue, specific examples to reference, clear statement of expectations, questions to understand their perspective), anticipate their response (likely explanations or excuses, how you'll respond to defensiveness, maintaining professional tone regardless), and arrange appropriate setting (private location away from members, sufficient time without interruption, neutral space not in front of mats).
Written notes help. Not reading from script, but having bullet points ensures you cover everything important and don't forget key examples when feeling nervous.
Conversation Structure: The Four-Step Framework
Step 1: State the Issue Clearly - Open with direct, clear statement of concern without ambiguity. 'I need to talk with you about punctuality. You've arrived at class start time rather than 15 minutes before on [date], [date], and [date]. This creates problems with class setup and member greeting.' Not 'I wanted to chat about how things are going' - that's vague and confusing.
Step 2: Provide Specific Examples - Back up concern with concrete facts, not vague generalities. 'On Tuesday you arrived at 7:00pm for the 7pm class. Members were waiting and I had to setup mats. On Thursday you arrived at 6:58pm. Today you arrived at 7:03pm.' Far more effective than 'You're often late' which invites argument about 'how often is often?'
Step 3: Listen to Their Perspective - After stating issue, pause and listen. 'Help me understand what's causing this.' They may have legitimate explanation (childcare issues, traffic problems, misunderstanding of expectations). Understanding doesn't excuse behaviour but informs solution. Give genuine opportunity to respond without interrupting or dismissing.
Step 4: Agree Action Plan - Collaboratively develop solution with specific commitments and timeline. 'Going forward, you'll arrive by 6:45pm for every class. If you'll be late, you'll text me by 6:30pm. If this continues, we'll need to have a formal disciplinary conversation. Does this seem reasonable?' Get explicit agreement. Follow up in writing summarising conversation and agreed actions.
Tone and Approach: Professional but Human
Balance firmness with respect: professional not personal (focus on behaviour and impact, not character or personality; 'Your lateness disrupts class preparation' not 'You're unreliable and unprofessional'), calm and measured (even if frustrated, maintain even tone; anger destroys productive conversation), clear and direct (don't soften message so much they miss the point; kind but unambiguous), empathetic but firm (acknowledge challenges they face, but expectations don't change; 'I understand traffic is difficult, but punctuality is essential'), and forward-focused (less dwelling on past failures, more on future improvement; what will change going forward).
Avoid phrases that trigger defensiveness: 'You always...' or 'You never...' (invites nitpicking exceptions), 'Everyone thinks...' (who's everyone? Feels like ganging up), 'I shouldn't have to tell you...' (condescending), 'If you cared about...' (questioning motivation), and 'This is your last chance' (unless it actually is, and you're prepared to follow through).
Documentation: Protect Yourself and Them
Document all difficult conversations in writing: date, time, and location of conversation, summary of issue discussed with specific examples, instructor's response or explanation, agreed action plan with specific steps and timeline, consequences discussed if no improvement, and follow-up date scheduled. Write up within 24 hours whilst fresh. Store securely and confidentially.
Send email summary to instructor: 'Following our conversation today, I wanted to confirm our discussion in writing. We talked about [issue]. You explained [their perspective]. We agreed [action plan]. I'll check in on [date] to review progress. Please confirm you received this and agree with the summary.' Keep their confirmation.
This documentation protects both parties. Protects you in employment tribunals by demonstrating you raised concerns clearly and fairly. Protects them by creating clear record of expectations so they can't claim they didn't know. Also jogs memories if situation recurs months later.
Follow-Up: Check Progress
Schedule specific follow-up to assess improvement: check-in date agreed during conversation (typically 2-4 weeks depending on issue severity), observation or evidence collection (observe their punctuality, teaching quality, attitude in action, don't rely solely on memory), positive reinforcement if improving (acknowledge progress explicitly; 'I've noticed you've been arriving at 6:45pm consistently. Thank you for making that change.'), further conversation if not improving (escalate to formal warning if appropriate, or reassess if perhaps the agreed solution wasn't realistic), and adjust approach if needed (if agreed solution isn't working for legitimate reasons, collaboratively find alternative, flexibility shows good faith).
Don't have difficult conversation and then never mention it again. Following up shows you're serious and gives opportunity to acknowledge improvement or escalate if necessary.
Addressing Specific Issues: Tactical Approaches
Different problems require tailored responses. The general framework above applies, but specific tactics help with common scenarios.
Poor Teaching Quality
Approach systematically: observe classes objectively (sit in on multiple classes, use objective criteria: clarity, engagement, safety, pacing, structure, take notes documenting specific strengths and weaknesses), provide specific constructive feedback ('Your warm-up was great, but the technique instruction moved too quickly. I noticed three beginners were lost by the second variation. Next time, check understanding before progressing'), offer training and support (shadowing experienced instructors, additional curriculum guidance, peer feedback and observation, external coaching courses if available), set improvement timeline (typically 4-8 weeks for teaching quality improvement, specific goals: 'Improve pacing to ensure beginners understand before progressing', check-ins every 2 weeks to assess progress), and evaluate after timeline (has teaching improved sufficiently?, member feedback and attendance in their classes, if no improvement despite support, may need to reassign to assistant role or end arrangement).
Document improvement plan in writing. Example: 'We've identified teaching pacing as development area. Over next 6 weeks, you'll shadow John's Tuesday class twice, implement regular understanding checks before progressing techniques, and receive feedback after every class. We'll review progress on [date].'
Unreliability: Lateness and Absences
Address directly and immediately: first occurrence (gentle reminder of expectations: 'Remember we need everyone 15 minutes before class'), second occurrence (direct conversation: 'This is the second time. What's causing this? Can you commit to 15 minutes before going forward?'), document pattern (dates, times, impact on gym operations, any explanations given), formal warning if continues (written warning following ACAS procedures: investigation, written allegations, hearing, decision), and understand root cause (childcare issues might be solvable through schedule adjustment, lack of commitment might require ending arrangement).
For persistent lateness without good reason, clear consequences: 'If you arrive after 6:50pm for a 7pm class, you'll need to find coverage and won't be paid for that class.' Financial consequences focus attention effectively.
Distinguish between someone struggling with legitimate challenges who's trying their best, versus someone who doesn't respect your time or gym. The first deserves support and flexibility. The second needs clear consequences or exit.
Negative Attitude
Explore root causes before judging: private conversation identifying underlying issues ('I've noticed you seem frustrated lately. What's going on?'), address legitimate concerns (if they're right about problem, fix it; 'You're right that the payment system is clunky. We're switching to [solution] next month'), set professional behaviour expectations regardless of grievances ('Even when you disagree with a decision, I need you to present united front to members and handle disagreement with me privately'), monitor improvement (is attitude shifting with support and resolution of legitimate concerns?), and recognise when it's fundamental incompatibility (some people are chronically negative; if they can't shift despite addressing concerns, they're toxic to culture).
Example conversation: 'I need to address something I've observed. Over the last month, I've heard you complain about our curriculum to members three times, and you've been negative about our new pricing structure. If you disagree with decisions, I'm open to discussing privately. But publicly undermining decisions damages member confidence. Can you commit to presenting professionally even when you disagree?'
If negativity continues despite clear expectations, part ways. One chronically negative instructor destroys morale across entire team and leaks negativity to members. Protecting your culture is paramount.
Undermining Leadership
Address immediately and unambiguously: private conversation as soon as you become aware ('I heard you told members you think our new schedule is stupid. When you contradict my decisions to members, it undermines my leadership and creates confusion.'), explain impact ('Members now don't know whether to follow the schedule or not. This creates chaos and makes me look incompetent.'), set clear expectation ('You can disagree with me privately. You must present united front publicly. Disagree privately, support publicly.'), document the conversation (written follow-up email confirming discussion and expectations), and escalate if continues (one occurrence might be mistake; pattern is insubordination requiring formal discipline).
This is non-negotiable boundary. An instructor who openly contradicts and undermines you creates impossible working environment. They either commit to professional conduct or they need to go.
Inappropriate Behaviour with Members
Requires immediate and serious response: investigate immediately upon receiving complaint or observing behaviour (speak to witnesses, gather facts, document thoroughly), suspend instructor pending investigation if allegation is serious (with pay if employee, prevents further risk whilst investigating), formal investigation following proper process (written allegations, opportunity to respond, hearing with right to be accompanied if employee), decide on appropriate response based on findings (if substantiated: dismissal likely for serious boundary violations, final warning for less serious but still inappropriate, if unsubstantiated: clear instructor and ensure malicious complaints addressed), and protect complainant and other members (ensure no retaliation, communicate outcome appropriately whilst respecting privacy).
Safeguarding issues involving children require additional steps: immediately report to designated safeguarding officer, report to local authority and police if safeguarding concern, follow procedures in your safeguarding policy, and seek specialist advice from safeguarding experts or insurers.
Take all complaints seriously even if you struggle to believe them. Investigate properly. Better to be seen as overcautious than negligent.
Planning to Leave or Open Competing Gym
Handle professionally even when feeling betrayed: have direct conversation about their plans ('I've heard you're planning to open your own gym. Can we discuss this?'), understand timeline ('When are you planning to leave? What's your notice period per our contract?'), enforce notice period (typically 1 month, allows time to arrange coverage and transition), ensure knowledge transfer (smooth handover of classes, member relationships, administrative responsibilities), consider non-compete enforcement (if you have one, typically 6-12 months within 5-10 miles; be reasonable in enforcement unless they're actively poaching), maintain professionalism (they'll remain part of BJJ community; parting on good terms benefits everyone long-term), and learn from the departure (exit interview: why are they leaving? What could be better? Even if planning to compete, their feedback might be valuable).
Many successful gym owners maintain friendly relationships with instructors who've left to open their own academies. BJJ community is small. Burning bridges creates enemies and bad reputation. Handling transitions gracefully creates allies and good reputation.
Some gym owners see instructor opening nearby gym as betrayal. Others see it as natural progression and even point of pride that they trained someone well enough to run their own operation. Your attitude shapes the relationship going forward.
UK Legal Considerations: Protecting Yourself
UK employment law provides significant protection to employees (less to contractors). Understanding legal requirements prevents costly tribunal claims.
Employment Status Matters
Employees have substantial protections including unfair dismissal protection (after 2 years employment under current law, reducing to 6 months from January 2027 under Employment Rights Act 2025), requirement to follow ACAS disciplinary procedures, redundancy pay entitlement, notice period requirements, and right to written reasons for dismissal.
Self-employed contractors have minimal protections: no unfair dismissal rights (can end contract per terms without formal procedures), no redundancy pay, no statutory sick pay or holiday pay, and contract simply ends per its terms (typically with notice period but less formal process).
This makes contractor classification attractive to employers. However, you cannot simply call someone a contractor if they're really an employee. HMRC uses IR35 tests assessing control, substitution, and mutuality of obligation. Misclassification carries penalties up to £60,000 per worker plus back-payments for National Insurance and pension. See our contractor vs employee guide.
ACAS Disciplinary Procedures (For Employees)
The ACAS Code of Practice sets minimum standards for handling disciplinary issues with employees. Failing to follow the Code increases employment tribunal awards by up to 25%. The procedure requires investigation (gather facts about performance issue or misconduct, speak to witnesses, collect evidence, keep contemporaneous notes), written notification (inform employee in writing of allegations, provide reasonable time to prepare response, typically 5 working days), disciplinary hearing (give opportunity to respond to allegations, allow employee to be accompanied by colleague or trade union representative, listen to their explanation and evidence), decision (decide outcome based on facts: no action, informal warning, written warning, final written warning, dismissal), notification in writing (confirm decision in writing with reasons, explain appeal rights), and right of appeal (employee can appeal decision, appeal heard by different manager if possible, appeal outcome confirmed in writing).
For minor issues, informal warning is appropriate. For more serious or repeated issues, progress through written warning, final written warning, then dismissal. For gross misconduct (serious safety violation, theft, assault, serious insubordination), dismissal after proper hearing may be justified even without prior warnings.
Performance Improvement Plans
PIPs provide structured approach to performance issues: written plan documenting specific performance problems with concrete examples, clear measurable objectives for improvement, timeline for improvement (typically 4-12 weeks depending on issue complexity), support and resources provided (training, mentoring, reduced workload, additional supervision), regular review meetings (weekly or fortnightly to assess progress, provide feedback, adjust plan if needed), documentation of progress or lack thereof (contemporaneous notes of observations, member feedback, improvement or continued problems), and decision point at end of period (has performance improved sufficiently to continue?, if yes: ongoing monitoring, if no: progress to formal warning or dismissal).
Example PIP extract: 'Performance Issue: Inconsistent class preparation and structure leading to member complaints. Specific Examples: [dates and details]. Improvement Required: Prepare written lesson plan 24 hours before each class, follow gym curriculum structure, arrive 15 minutes before class prepared to teach. Support Provided: Shadow John's classes twice weekly for two weeks, weekly feedback meetings with gym owner, access to curriculum materials and templates. Timeline: 6 weeks from [date] to [date]. Review: Weekly check-ins every Tuesday, final review on [date].'
Unfair Dismissal Risks
Employees with 2+ years service (reducing to 6+ months from January 2027) can claim unfair dismissal if dismissed without fair reason or proper procedure. Fair reasons for dismissal include capability (inability to do job despite support and training), conduct (misconduct such as lateness, insubordination, policy violations), redundancy (genuine business need to reduce costs or headcount), statutory restriction (e.g., losing right to work in UK), and some other substantial reason (fundamental breakdown in trust).
Automatically unfair reasons (no service requirement) include discrimination, pregnancy and maternity, whistleblowing, health and safety concerns, asserting statutory rights, and trade union activities.
Following proper ACAS procedure doesn't guarantee you'll win tribunal, but not following it almost guarantees you'll lose. Compensation for unfair dismissal is currently capped at 12 months' pay or £118,233, whichever is lower. However, the Employment Rights Act 2025 removes this cap, potentially increasing awards significantly from January 2027 onwards.
Constructive Dismissal: Don't Push Them Out
Constructive dismissal occurs when employer's behaviour is so unreasonable that employee feels forced to resign, then claims they were effectively dismissed. Common scenarios include unilaterally cutting pay or hours, demoting without justification, creating hostile environment through bullying or harassment, making false accusations or unwarranted disciplinary actions, and removing responsibilities or marginalising the employee.
Gym owner frustrated with underperforming instructor who reduces their classes from 6 to 1 per week without agreement, hoping they'll quit, risks constructive dismissal claim. The instructor can claim they were forced out and pursue unfair dismissal.
If someone needs to go, follow proper procedure and dismiss them fairly. Don't try to make their life miserable so they quit. It's both unethical and legally risky. See ACAS guidance on constructive dismissal.
When to Get Legal Advice
Consult employment solicitor before dismissing employees (cost £200-£500 for consultation, far cheaper than tribunal awards), when facing serious allegations (safeguarding, discrimination, whistleblowing), when employee threatens tribunal claim (solicitor can assess risks and advise on settlement), for settlement agreement negotiation (paying employee to leave without tribunal), when unsure about procedure (better to ask than guess and get it wrong), and for complex situations (mental health issues, long-service employees, sensitive circumstances).
Peninsula, Ellis Whittam, and similar HR consultancies offer fixed-fee employment law advice (£100-£200 monthly) with tribunal defence cover. For gyms with multiple employees, this insurance provides peace of mind.
Don't use ChatGPT or Google for employment law advice. Law is nuanced and fact-specific. A solicitor's £300 fee for reviewing your dismissal plan is excellent value compared to £10,000+ tribunal award.
Documentation: Your Best Protection
In employment disputes, if it isn't documented, it didn't happen. Thorough documentation is your primary defence.
What to document: all performance issues and incidents (date, time, what happened, who witnessed, impact on gym), all conversations about performance (formal and informal, what was said, what was agreed, follow-up actions), warnings given (informal, written, final written, reasons, improvement required, consequences if no improvement), training and support provided (what help offered, when, instructor's response), member complaints or feedback (positive and negative, specific quotes or details, how addressed), attendance and punctuality records (late arrivals, absences, patterns over time), policy violations (which policy violated, specific details, previous violations of same policy), and agreed action plans and improvement plans (specific commitments, timelines, review dates).
How to document effectively: contemporaneous notes (record within 24 hours whilst memory fresh, brief but specific facts), objective and factual (not 'John was acting like a jerk', but 'John raised his voice and used profanity when I gave feedback'), specific dates, times, witnesses (concrete details not vague generalities), follow up conversations in writing (email summarising discussion and agreements), keep securely and confidentially (locked cabinet or password-protected files, limited access to authorised personnel only), GDPR compliance (don't share inappropriately, instructor has right to see information held about them, retain only as long as needed per policy), and retain for appropriate period (typically 6 years for employment records in UK, indefinitely for serious matters like safeguarding).
Example documentation: 'Date: 15/01/2026, Time: 6:45pm, Issue: Late arrival. Instructor arrived at 7:02pm for 7:00pm class (his third late arrival this month). Members Jane and Michael were waiting on mats. I had to setup equipment and greet members instead of preparing in office. Conversation: I spoke to instructor privately at 8:35pm after class. I showed him record of arrival times (3rd, 8th, and 15th January). He apologised and cited traffic. I reminded him of expectation to arrive 6:45pm and asked if he could commit to this. He confirmed he could. I explained that if lateness continues, we'll move to formal written warning per disciplinary policy. He acknowledged understanding. Follow-up: Emailed summary at 9:15pm and requested confirmation (email attached). Next review: 29/01/2026 - will assess punctuality over next 2 weeks.'
When to Part Ways: Recognising the End
Sometimes relationships cannot be salvaged. Knowing when to end an arrangement prevents prolonging inevitable and protects your gym.
Valid reasons to part ways: exhausted all reasonable options (provided clear expectations, training, support, feedback, improvement opportunities; no meaningful progress despite efforts), no improvement despite support (you've given fair chance and appropriate timeline; performance or behaviour hasn't improved), serious misconduct (gross misconduct justifying immediate dismissal after proper hearing: serious safety violation, theft, assault, gross insubordination, serious boundary violation with members), incompatible values or culture (fundamental misalignment on what matters; you value professionalism and inclusivity, they don't share those values; culture fit cannot be trained), business necessity (genuine need to reduce costs; gym revenue doesn't support current instructor expenses; redundancy situation), and trust breakdown (relationship deteriorated beyond repair; you cannot rely on them; they cannot work professionally with you or team).
Don't end relationships solely because someone annoys you or isn't perfect. Everyone has quirks. Ask yourself: Is this person fundamentally damaging my gym? Have I genuinely given them fair chance to improve? Have I been clear about expectations and consequences? Am I acting fairly and reasonably?
If answers are yes, ending the arrangement is appropriate. If answers are no, perhaps the issue is your management rather than their performance.
The Exit Process: Parting Professionally
Handle departures with dignity regardless of circumstances.
For Employees: Follow Proper Procedure
Dismissing employees requires following ACAS procedure: investigation and hearing (gather facts, provide written allegations, hold hearing with opportunity to respond), written decision (confirm dismissal in writing with reasons, explain appeal rights), notice period (pay per contract, typically 1 month for instructors; can be pay in lieu of notice if don't want them working), final pay calculation (salary or wages owed, payment for unused holiday, deduct any amounts owed to you), tax and National Insurance (process final PAYE properly, provide P45), appeal (allow appeal if requested, hear appeal fairly, confirm outcome), and reference policy (decide whether you'll provide reference, stick to factual information to avoid defamation).
Example dismissal letter: 'Dear [Name], Following the disciplinary hearing on [date], I am writing to confirm the decision to terminate your employment as BJJ Instructor with [Gym Name], effective [date]. The reason for dismissal is [reason: e.g., continued poor performance despite support and warnings, as detailed in hearing]. This decision follows [summary of procedure: warnings, PIP, support provided]. Your notice period is [X weeks] per your contract. Your final working day will be [date] and you will receive pay for this notice period. You will receive final pay on [date] including [X] days unused holiday pay. Please return [keys, equipment, etc.] by [date]. You have the right to appeal this decision by writing to [person] within [X days]. Yours sincerely, [Your Name]'
For Contractors: Simpler Process
Ending contractor arrangements is simpler: notice per contract (typically 1 month, provide written notice), final payment (pay for work completed, no holiday pay as contractor), return of equipment (keys, branded clothing, any gym property), written confirmation (brief letter or email confirming end of arrangement), no ACAS procedures required (contractors aren't employees, so formal disciplinary procedures don't apply), and be professional (even though legally simpler, treat with respect and dignity).
Example contractor termination: 'Dear [Name], I am writing to confirm that we will no longer require your services as BJJ Instructor after [date], per the notice period in our agreement dated [date]. Your final classes will be [specific dates and times]. You will receive payment for all classes taught through [date] on our normal payment cycle of [date]. Please return all keys and any gym property by [date]. Thank you for your contributions to the gym. I wish you well in your future teaching opportunities. Best regards, [Your Name]'
Communication to Members
Handle member communication carefully: brief and factual (don't share details of performance issues or reasons, privacy considerations for instructor, members don't need full story), focus on continuity ('Instructor X is leaving. Their Tuesday and Thursday classes will be taught by [replacement]. Quality instruction continues.'), avoid badmouthing (even if departure was difficult, taking high road protects your reputation, members respect professionalism), allow instructor to say goodbye if appropriate (if departure is amicable and instructor wants to, allow brief farewell, if departure is acrimonious, better to make clean break), and reassure members (some may be concerned about changes, emphasise continuity and commitment to quality).
Example member announcement: 'Quick update: Instructor John will be finishing up at the gym this month. His last class will be Thursday 30th. Starting in February, Sarah will be teaching John's Tuesday and Thursday sessions. Sarah brings 8 years BJJ experience and excellent teaching skills. We're excited to have her. If you have questions, please let me know.'
When Instructor Resigns
Most departures are resignations rather than dismissals: accept gracefully (don't guilt trip or beg them to stay if mind's made up, professionalism benefits everyone), conduct exit interview (why are they leaving?, what could be better?, feedback might be valuable even if it stings), enforce notice period (per contract, typically 1 month, ensure smooth transition), knowledge transfer (handover of classes, member relationships, admin responsibilities, document anything only they know), maintain professional relationship (they'll remain in BJJ community, part on good terms benefits both long-term), non-compete enforcement (if applicable, enforce reasonably, don't be aggressive unless actively recruiting your members), and provide reference if appropriate (factual reference covering dates of engagement, role, responsibilities).
Example resignation response: 'Thank you for letting me know. I understand your decision and wish you well. To ensure smooth transition, please confirm your last working day per our contract's notice period is [date]. I'd like to schedule a handover meeting next week to discuss class coverage and member introductions to your replacement. I'd also appreciate a brief exit conversation to learn from your experience here. Thank you for your contributions over the past [time period]. I've valued having you on the team.'
Self-Reflection: When You're Actually the Problem
Sometimes the 'difficult instructor' isn't the problem - your management is. Honest self-assessment prevents wrongly blaming instructors for issues you created.
Questions to ask yourself: Have I communicated expectations clearly in writing? (Instructors cannot meet expectations they don't know about. Assuming they 'should know' isn't management.) Have I provided adequate training and support? (Throwing someone into teaching without guidance then criticising their methods is unfair.) Do I give regular feedback or only criticise when frustrated? (Instructors need ongoing feedback, not silence followed by explosion.) Am I consistent in applying policies or do I have favourites? (Inconsistency breeds resentment. If you let one instructor arrive late but discipline another, you're the problem.) Have I listened to their concerns or dismissed them? (Instructors who feel unheard become disengaged. Sometimes they're right and you need to change.) Am I paying fairly or taking advantage? (Underpaying by £10/class then wondering why they're not fully committed is naive.) Do I treat instructors with respect or as interchangeable resources? (People respond to how they're treated. Respect generates loyalty; disrespect generates problems.) Am I micromanaging or trusting them to teach their way? (Hiring experienced instructors then dictating every detail creates frustration. If you wanted clones, you shouldn't have hired thinking humans.)
If multiple instructors have similar complaints or issues, the common denominator is you. Listen to patterns. If every instructor you hire eventually becomes 'difficult', maybe you're creating difficulty through poor management, unclear expectations, lack of support, or unreasonable demands.
One gym owner realised after his fourth instructor quit within a year that the problem wasn't finding 'good instructors' - it was his management style. He was critical, never positive, changed policies without communication, and paid below market rate. His current instructors, hired after he changed his approach based on exit interview feedback, have stayed 3+ years with no 'difficulty'.

Frequently Asked Questions
How do I handle an instructor who's consistently late to classes?
Address immediately after first or second occurrence. Document dates and times. Have direct conversation explaining impact and expectation (15 minutes before class). If pattern continues, implement progressive discipline: informal warning, written warning, final warning, dismissal. For contractors, clear consequences like 'arrive after class start time, you're not paid for that class' focuses attention. Document all conversations and follow ACAS procedures for employees.
Can I fire an instructor without warning in the UK?
For contractors, yes - end contract per its notice terms (typically 1 month notice). For employees, dismissal without warnings is only justified for gross misconduct (serious safety violation, theft, assault) after proper investigation and hearing. Normal performance issues require progressive warnings following ACAS Code. Employees with 2+ years service can claim unfair dismissal (reducing to 6+ months from January 2027).
What should I do if an instructor is inappropriate with members?
Investigate immediately. Suspend pending investigation if allegation is serious. Gather facts from witnesses. Hold disciplinary hearing following proper procedure. If substantiated, dismissal is appropriate for serious boundary violations. For safeguarding concerns involving children, report to designated safeguarding officer, local authority, and police. Document thoroughly. Protect complainant from retaliation. Take all complaints seriously even if you struggle to believe them.
How do I document performance issues with instructors?
Record contemporaneously (within 24 hours) with specific facts: date, time, what happened, witnesses, impact. Document all conversations about performance, warnings given, support provided, member feedback, attendance records, policy violations. Write objectively not emotionally ('John arrived at 7:05pm for 7pm class, his third late arrival this month' not 'John doesn't care about punctuality'). Follow up conversations in writing via email. Store securely following GDPR. Retain 6 years minimum.
What's a Performance Improvement Plan and when should I use it?
A PIP is structured written plan addressing performance problems. Use when instructor's teaching quality, reliability, or professionalism isn't meeting standards despite feedback. Include specific problems with examples, clear measurable improvement objectives, timeline (4-12 weeks), support provided, regular review meetings, and consequences if no improvement. PIPs demonstrate fairness and document your efforts before escalating to formal warnings or dismissal.
Can I stop an instructor from teaching at other gyms?
Only if you have enforceable non-compete clause in contract. Non-competes must be reasonable in scope and duration (typically 6-12 months within 5-10 miles) to be enforceable in UK courts. You cannot prohibit someone from earning a living indefinitely. For contractors, restricting where they work is difficult as contradicts genuine self-employment. Attempting overly broad restrictions makes entire clause unenforceable.
What are my legal obligations when dismissing an instructor in the UK?
For employees: follow ACAS disciplinary procedures (investigate, written allegations, hearing, decision, appeal right), provide written confirmation with reasons, pay notice period or pay in lieu, calculate final pay including unused holiday, process final PAYE and provide P45. For contractors: provide notice per contract terms, pay for work completed, no holiday pay. Failing to follow ACAS Code increases tribunal awards by up to 25%.
How do I handle an instructor who's planning to open their own gym?
Have professional conversation about their plans and timeline. Enforce contract notice period (typically 1 month). Ensure smooth knowledge transfer and class coverage. Consider non-compete enforcement if applicable - be reasonable unless actively recruiting your members. Maintain professionalism even if feeling betrayed. BJJ community is small and burning bridges creates enemies. Many successful owners maintain friendly relationships with former instructors who opened their own gyms.
What's constructive dismissal and how do I avoid it?
Constructive dismissal is when employer behaviour is so unreasonable employee feels forced to resign, then claims unfair dismissal. Avoid by not unilaterally cutting pay or hours, not creating hostile environment through bullying, not making false accusations, not marginalising employee hoping they'll quit. If someone needs to go, follow proper dismissal procedure fairly. Don't try to push them out. See ACAS guidance on constructive dismissal.
When should I get legal advice about instructor problems?
Consult employment solicitor before dismissing any employee (£200-£500 consultation far cheaper than tribunal awards), when facing serious allegations (safeguarding, discrimination, whistleblowing), when employee threatens tribunal, for settlement agreement negotiation, when unsure about procedure, or for complex situations (mental health, long-service employees). Consider Peninsula or Ellis Whittam fixed-fee HR services (£100-£200/month) with tribunal defence cover for ongoing support.
