Employment Tribunal Claims Guide: Unfair Dismissal & Discrimination 2026

Published: October 2026 | Read Time: 12 minutes

Employment Tribunal Basics

Employment Tribunals are independent judicial bodies established under Employment Tribunals Act 1996, hearing employment disputes between workers and employers. These specialist courts handle diverse claims ranging from unfair dismissal to wage disputes, discrimination, harassment, and breach of employment contract. UK tribunal system processes approximately 70,000 claims annually. Most cases settled before hearing (70-80%), with tribunal judges highly experienced in employment law matters. Tribunals designed to be accessible to unrepresented claimants, though representation increasingly common with complex cases.

Structure and Jurisdiction of Employment Tribunals

Each tribunal consists of legally qualified judge (Employment Judge) plus two lay members with employment relations experience (from employer and employee backgrounds). Tribunals sit in regional centers across UK. Claims can involve: contract disputes, wrongful or unfair dismissal, discrimination on protected grounds, harassment, victimization, wage/holiday pay disputes, breach of employment contract, whistleblowing retaliation, maternity/paternity rights violations, working time directive breaches. Tribunal jurisdiction limited—certain claims must go to civil court (personal injury at work, defamation, breach of non-disclosure agreements).

Claimant Rights and Protections

• File Claim Free: No court filing fees (unlike civil courts charging hundreds of pounds). Access to justice ensured regardless of claimant’s financial position.
• Representation Options: Represent yourself, hire solicitor specializing in employment law, use barrister, or have trade union representative or friend support you (though friends cannot provide legal advice).
• Hearing Attendance Flexibility: Attend hearing in person, via video conference, or telephone (increasingly common post-pandemic). Accommodations for disabled claimants.
• Evidence Presentation: Present documentary evidence, witnesses, expert reports. Tribunal cross-examines witnesses. Claimant controls evidence strategy.
• Appeal Rights: Appeal tribunal decision to Employment Appeal Tribunal (higher court) if legal error identified. Not all decisions appealable—factual errors not grounds for appeal.
• Confidentiality Protection: Sensitive information (medical records, settlement discussions, witness details) can be heard in private/confidential sessions.

Unfair Dismissal Claims

Understanding Unfair Dismissal Under UK Law

Unfair dismissal claim arises when employer terminates employment contract without valid reason or fails to follow fair dismissal procedure. Employment Rights Act 1996 Section 98 establishes framework: employer must have valid reason (capability, conduct, redundancy, statutory bar, some other substantial reason) AND follow fair procedure. Claimant must have 2+ years continuous employment (reduced to any period for discriminatory dismissals or whistleblowing). If both conditions met, dismissal fair; if either fails, dismissal unfair and compensation awarded.

What Qualifies as Unfair Dismissal – Detailed Analysis

• Dismissed Without Proper Procedure: Employer terminated employment without following fair dismissal process. Includes: dismissal without any investigation into allegations, dismissed immediately without warnings or opportunity to improve, dismissed without disciplinary hearing where employee can present defense, dismissed without right to appeal decision. Procedural unfairness alone (even if substantively justified) renders dismissal unfair.
• Dismissed for Protected Reason: Automatically unfair to dismiss for: public interest whistleblowing (reporting illegal/dangerous activity), union membership/activities, health and safety concerns (refusing unsafe work), pregnancy/maternity, taking family leave, jury duty, participating in workforce consultation. Protected reasons override requirement for 2 years service—even week-old employee protected.
• Discriminatory Dismissal: Dismissed because of age, disability, gender, race, religion, sexual orientation, gender reassignment, marriage/civil partnership, or pregnancy. Automatically unfair regardless of years service. Employer cannot justify discriminatory dismissal with legitimate business reason.
• Constructive Dismissal: Technically resign but claim unfair dismissal because employer fundamentally breached employment contract, making continued employment untenable. Examples: substantial pay cut without consent, demotion without agreement, workplace harassment/bullying creating intolerable environment, employer failure to provide safe workplace, breach of express contractual terms. Must prove breach was serious enough to justify resignation (not minor inconvenience).
• Dismissed for Taking Family Leave: Automatically unfair to dismiss for taking parental leave, adoption leave, surrogacy leave, or shared parental leave. Includes discrimination regarding part-time return or flexible working requests following leave.
• Dismissed for Medical Reasons Without Considering Alternatives: If dismissal due to illness/disability, employer must consider reasonable adjustments, redeployment, alternative roles before dismissal. Failure to explore alternatives renders dismissal unfair (though genuine inability to accommodate can justify dismissal).
• Inconsistent or Discriminatory Enforcement: Dismissed for conduct while other employees guilty of identical conduct not dismissed. Unequal treatment indicates unfair dismissal, particularly if pattern shows discrimination based on protected characteristic.

Establishing Unfair Dismissal – The Legal Test

Step 1 – Prove Employment Relationship: Claimant must prove they were employee (not contractor/self-employed) of respondent. Employment contract, payroll records, tax documents establish employment.

Step 2 – Prove Dismissal Occurred: Employer terminated employment (including constructive dismissal where employee forced to resign). Resignation accepted under duress, wrongful notice period, or fundamental breach constitutes constructive dismissal.

Step 3 – Prove Dismissal Unfair: Burden initially on claimant to prove dismissal occurred. Burden then shifts to employer to prove: valid reason for dismissal existed, fair procedure followed. If employer cannot establish both, dismissal unfair.

Step 4 – Mitigation Assessment: Tribunal considers whether claimant failed to mitigate losses (seek alternative employment, return to work when able). Damages reduced if claimant unreasonably failed to minimize losses.

Discrimination Claims

Equality Act 2010 – Protected Characteristics

Equality Act 2010 protects workers from discrimination based on nine protected characteristics. Discrimination on these grounds is unlawful across employment (and beyond). Protected characteristics include:

• Age: Discrimination against workers of particular age or age group. Includes mandatory retirement ages (generally unlawful unless justified).
• Disability: Discrimination against employees with physical/mental disabilities. Includes failure to provide reasonable adjustments to accommodate disability.
• Gender Reassignment: Discrimination against transgender individuals. Protection applies during, after, and before transition process.
• Marriage and Civil Partnership: Discrimination based on marital status or civil partnership status. Single/married/partnered employees all protected equally.
• Pregnancy and Maternity: Discrimination against pregnant employees or those on maternity leave. Automatic unfairness to dismiss for pregnancy-related reasons.
• Race and Ethnicity: Discrimination based on race, color, nationality, ethnic origin. Includes national origin and immigration status.
• Religion or Belief: Discrimination based on religion (or philosophical belief). Includes atheism, agnosticism, veganism (as moral philosophy).
• Sex: Discrimination based on gender (male/female). Includes sexual harassment creating hostile work environment.
• Sexual Orientation: Discrimination based on sexual orientation (heterosexual, homosexual, bisexual). Includes perceived orientation discrimination.

Types of Discrimination – Detailed Breakdown

• Direct Discrimination: Employer treats person worse explicitly because of protected characteristic. Example: refusing promotion to woman, lower pay for employee of certain race, rejecting job applicant due to age. Direct discrimination rarely justified—employer must prove legitimate occupational requirement applied (very narrow exception).
• Indirect Discrimination: Employer applies neutral policy that disadvantages people with protected characteristic more than others. Example: requiring all employees to work full-time disadvantages parents (more likely women), or scheduling all meetings during prayer times disadvantages religious workers. Indirect discrimination can be justified if employer proves legitimate business reason and proportionate means to achieve aim.
• Harassment: Unwanted conduct related to protected characteristic creating hostile, intimidating, offensive work environment. Includes sexual harassment, racist comments, mocking disability, religious mockery. Single incident can constitute harassment if sufficiently serious; pattern of lower-level incidents also constitutes harassment if cumulative effect hostile.
• Victimization: Retaliation against employee for raising discrimination complaint or participating in discrimination case. Employer cannot dismiss, demote, or treat unfavorably employee who complained about discrimination or gave evidence in discrimination case. Protected from retaliation even if original discrimination complaint failed.
• Discrimination by Association: Discrimination based on association with person with protected characteristic. Example: refusing to hire because applicant’s sibling is disabled, or treating employee badly because their spouse is of particular race/religion.
• Perceived Discrimination: Discrimination based on perception/assumption about protected characteristic, even if assumption incorrect. Example: assuming employee is disabled based on appearance, assuming employee’s religion, assuming sexual orientation based on mannerisms.

Compensation Components – Detailed Breakdown

Lost Earnings (Past): Gross wages from dismissal date to tribunal hearing or settlement date. Includes base salary, regular bonuses, overtime pay, commission, benefits (pension contributions, health insurance, car allowance). Calculated as: weekly gross pay × number of weeks from dismissal to settlement/hearing. Claimant has duty to mitigate—reduce award if they unreasonably failed to seek alternative employment during this period.

Future Loss (Loss of Earning Capacity): Estimated loss of earnings going forward if claimant unable to secure equivalent employment. Tribunal considers: difficulty finding similar work in claimant’s field, age (older workers find employment harder), length of unemployment, job market conditions in region. Typically calculated as percentage of salary over reasonable period (e.g., 70% of salary for 12 months, 50% for next 12 months). Can be substantial for older workers or specialist roles.

Pension Loss: Employer contributions to pension scheme lost due to dismissal. Includes: employer matching contributions, death benefit insurance (if employer-provided), pension tax relief value. Actuaries sometimes calculate actuarial pension loss value if significant.

Benefits Loss: Value of lost benefits: health insurance, car allowance, gym membership, life insurance, relocation allowances, professional fees. Typically calculated as monthly value × number of months from dismissal to comparable employment obtained.

Non-Pecuniary Loss (Injury to Feelings): Compensation for emotional distress, humiliation, embarrassment, injury to feelings caused by dismissal/discrimination. This is where discrimination claims diverge significantly from unfair dismissal (larger awards possible). Tribunals use guidelines assessing: severity of discrimination, duration, psychological impact, medical evidence of distress. Serious ongoing discrimination can warrant £20,000-£50,000+ injury to feelings awards.

Aggravated Damages: Additional compensation if employer’s conduct during tribunal process was particularly egregious—lying in tribunal, continuing harassment, attempting to intimidate witness. Adds 10-20% to award or separate award of £2,000-£10,000.

Time Limits and Procedural Requirements

Main Time Limit: 3 Months from Triggering Event

Most employment claims must be filed within 3 months (plus 5-day grace period for postal filing) of: dismissal date (for unfair dismissal), last discriminatory act (for discrimination claims), last unpaid wage date (for wage disputes), or last leave denial (for family leave claims). Missing this deadline bars claim entirely in vast majority of cases—tribunal has no discretion to extend for mere lateness. Time runs from triggering event, not from when claimant becomes aware of claim—ignorance of rights not excuse.

When Time Limit Starts Running

Dismissal Claims: From dismissal effective date (when termination takes effect), not date notice given or letter received. If given month’s notice, time runs from end of notice period.

Discrimination Claims: Time restarts with each discriminatory act (ongoing harassment). If employer makes final discriminatory decision (dismissal based on discrimination), time runs from dismissal. However, if pattern of smaller discriminatory acts building to final event, each incident may extend time limit forward.

Wage/Pay Claims: Time runs from date payment due and unpaid. Repeated non-payment extends time limit forward (each month unpaid wage is separate breach).

Extension in Exceptional Circumstances

Tribunal has discretion to extend 3-month deadline in exceptional circumstances: claimant prevented from filing by tribunal administrative error, claimant unaware of rights (must show reasonable unawareness—mere ignorance insufficient), claimant lacked mental capacity to pursue claim, legal advice provided misleading information preventing timely filing, continuing discrimination/ongoing breach extending deadline. These extensions rare—tribunal requires compelling evidence of exceptional circumstances. Claimants should not rely on extension possibility.

Continuing Breach Doctrine

Harassment and discrimination claims benefit from “continuing breach” doctrine—ongoing discriminatory conduct extends time limit. If employer subjects employee to repeated harassment over months/years, time runs from last incident, not first. Claimant can include earlier incidents in single claim even if technically outside 3-month window, provided recent incident within time limit.

Early Conciliation Requirement (ACAS Notification)

Before filing employment tribunal claim, claimant must notify ACAS (Advisory, Conciliation and Arbitration Service). ACAS attempts to resolve dispute without tribunal. This pause period (typically 30 days but can extend) extends time limit forward—claimant has 30 days after ACAS notifies matter settled/unresolved to file tribunal claim. Failure to notify ACAS first renders claim invalid.

Tribunal Process – Step by Step

Step 1: ACAS Early Conciliation (Mandatory)

Before filing tribunal claim, notify ACAS. Can be done online (tribunals.service.gov.uk) or by phone. ACAS conciliator assigned to attempt settlement without tribunal hearing. Conciliator contacts both parties, discusses dispute, explores settlement possibilities. Claimant and employer can agree settlement with ACAS support (binding once agreed). If no settlement reached within 30 days (extendable), ACAS issues certificate allowing tribunal claim filing. Process adds 4-8 weeks but often results in settlement, saving time/costs.

Step 2: Issue Tribunal Claim (ET1 Form)

File ET1 form (claim form) with tribunal online or by post. Form requires: respondent details, employment dates, job title, gross weekly pay, details of claim (which rights/laws breached), narrative of events leading to claim, compensation sought. Must include ACAS certificate number proving early conciliation attempted. Processing fee free (claimants pay nothing). Tribunal issues form to respondent (employer) who then must respond. Claim must be clearly written—tribunal won’t interpret vague allegations. Supporting documents (contract, emails, witness statements) attached.

Step 3: Respondent Response (ET3 Form)

Employer has exactly 28 days from service of ET1 to file ET3 (response form). Response contains employer’s version of events, admission/denial of facts, legal arguments supporting their position. Late responses accepted only in exceptional circumstances (tribunal can extend deadline by up to 28 additional days). If employer fails to respond timely without excuse, tribunal may make default judgment (finding employer in breach without hearing). Employer typically hires solicitor/HR advisor to prepare response—claimants often intimidated by detailed legal response.

Step 4: Case Management and Track Allocation

Tribunal allocates case to procedural track: Fast Track (Single): Simple cases decided by single Employment Judge on written evidence without hearing (decision within weeks). Used for straightforward claims with clear evidence. Standard Track: Complex cases requiring full hearing before judge and lay members. Judge manages case through preliminary orders—may require: document disclosure (both parties exchange evidence), witness statement exchange (written statements from proposed witnesses), expert reports (medical evidence for discrimination claims), clarification of legal issues. Case management conferences held (phone/in-person) to clarify issues, encourage settlement, set hearing date. Parties must comply with procedural orders or face sanctions (costs awards, dismissal).

Step 5: Pre-Hearing Review or Preliminary Hearing (If Needed)

Optional hearing (usually by phone) to: clarify disputed issues, explore settlement possibilities, determine if claim has reasonable prospects of success. If claimant’s claim appears to have no reasonable prospect of success, tribunal may issue warning that case will likely fail. Warning gives claimant chance to withdraw/settle. Preliminary hearings also used to decide jurisdictional issues (whether tribunal has power to hear claim) or procedural matters (document disputes).

Step 6: Final Substantive Hearing

Tribunal hearing where evidence presented and judgment made. Typical hearing format: Judge and two lay members sit. Respondent’s (employer’s) case presented first (claimant sits and listens). Employer’s witness(es) give evidence, can be cross-examined by claimant. Then claimant’s case presented—claimant and witnesses give evidence, employer cross-examines. Both sides make closing legal arguments. Hearing typically lasts 1-5 days depending on complexity (simple dismissal 1 day; complex discrimination 5+ days). Hearing public unless sensitive evidence heard in private.

Step 7: Judgment and Written Reasons

Tribunal issues judgment (decision on liability) either same day (simple cases) or within weeks (complex cases). Judgment states: whether claimant proved claim, reasoning, compensation awarded (if successful). Written reasons must address key evidence, legal principles applied, tribunal’s findings of fact. Losing party has 42 days to appeal to Employment Appeal Tribunal if legal error identified (factual findings generally not appealable). If claimant successful, respondent must pay compensation within set timeframe (typically 28 days), plus interest, plus any awarded costs.

Legal Representation and Costs

Self-Representation (Pro Se)

Many claimants represent themselves—UK tribunals designed to be accessible without lawyers. Advantages: save legal costs (no solicitor fees), complete control over strategy, flexible approach. Disadvantages: employment law complex, employers often represented by experienced solicitors giving significant advantage, mistakes in procedure/evidence can destroy case, settlement negotiations less effective against professional negotiators. Claimants should attend tribunal with organized documents, clear narrative, and witnesses if needed. Tribunal judge usually explains procedure and tries to ensure claimant fair treatment despite lack of representation, but cannot provide legal advice.

Trade Union or Citizens Advice Representative

Many claimants supported by trade union representative (if union member) or Citizens Advice lawyer (free). Representatives cannot provide formal legal advice but can support claimant through process, help prepare evidence, attend hearing. Union representatives often experienced in employment matters—valuable support at no cost. Citizens Advice Bureau provides free advice and representation in some cases (means-tested).

Solicitor Representation

Employment solicitor specializing in employment law represents claimant from claim filing through hearing and appeal if needed. Costs: £1,500-£5,000+ depending on case complexity, time invested, whether case involves hearings. Some solicitors work on conditional fee basis (no win, no fee)—no upfront cost, but take 15-25% of compensation if successful. Advantages of solicitor: expert knowledge of law, professional negotiation with employer’s solicitor, strategic planning, evidence preparation. Many employers back down or settle significantly when claimant has solicitor (indicates seriousness). Disadvantage: significant cost if not on no-win-no-fee basis.

Barrister Representation

Senior legal counsel (barrister) provides specialist representation, particularly for complex cases or appeals. Cost: £2,000-£10,000+ for hearing. Barristers typically hired through solicitor (not directly). Used when: case highly technical, involves novel legal issues, claimant already lost before tribunal and appealing, discrimination claim particularly complex. Direct access barristers can be hired directly by claimant in some cases (cost still high).

Cost Awards in Tribunal Cases

Unlike civil courts, tribunal cost awards rare. Tribunal can award costs against claimant who acts unreasonably: brings vexatious claims, ignores tribunal orders, makes false allegations, pursues claim knowing no reasonable prospects. Costs awarded to respondent only if claimant’s conduct unreasonable (not merely because claimant lost case). Cost awards typically modest (£1,000-£5,000) unless particularly egregious conduct. Respondent cannot recover solicitor fees from claimant unless special circumstances prove claimant knew case hopeless. This protects claimants who lose from facing additional £5,000+ legal bills.

Frequently Asked Questions

Do I Automatically Lose If I Resigned Rather Than Got Dismissed?

Not necessarily. Constructive dismissal applies when you resign due to employer’s serious breach of contract making continued employment intolerable. Example: significant pay cut without agreement, sudden demotion, workplace harassment creating hostile environment. Burden on you to prove employer’s conduct was fundamentally breaching contract, not minor inconvenience. If you resign simply because you dislike job, no constructive dismissal. However, if you have documented pattern of employer’s unacceptable conduct forcing resignation, strong claim exists. Constructive dismissal awards similar to unfair dismissal (£5,000-£25,000).

Can I Work for Competitor During Tribunal Claim?

Yes, no legal restriction on working for competitor. However, may significantly affect damages. Tribunal reduces award if you found comparable employment quickly (reduces “lost earnings” component). Example: if dismissed £40,000/year job but found equivalent £40,000/year role within 2 months, damages reduced substantially (lost only 2 months’ pay). Tribunal assesses whether failure to find comparable work was unreasonable. If job market poor and competitor role unavailable, tribunal likely accepts long unemployment period. Claimant has duty to mitigate losses by seeking alternative employment.

Is Tribunal Hearing Public or Private?

Hearings public by default—members of public and media can attend and observe. However, tribunal judge can hold hearing in private for sensitive evidence: medical records (disability/health conditions), confidential business information, identity of witnesses if security concerns exist. Private hearing requires application and judicial approval. Judgment always public (published with names and details unless anonymity order granted in exceptional circumstances—very rare).

What Happens If I Lose—Can I Appeal?

Appeal possible but narrow grounds exist. Can appeal if tribunal made legal error (misinterpreted law, wrong legal test applied), not if tribunal made factual findings you disagree with. Appeal filed with Employment Appeal Tribunal (higher court) within 42 days of judgment. Appeal success rate approximately 15%—most appeals fail because tribunal’s factual findings upheld even if harsh. Appeals expensive (legal costs £3,000-£10,000+), time-consuming (12-18 months), with uncertain outcome. Most losing claimants accept tribunal judgment rather than pursue appeal.

How Long Will My Case Take?

Timeline varies significantly: ACAS early conciliation 4-8 weeks, claim filing to hearing 6-12 months (longer if complex), hearing to judgment 2-8 weeks. Total simple claim: 6-14 months; complex discrimination case: 18-24+ months. Factors affecting speed: case complexity, whether parties cooperate/settle, tribunal schedule availability, evidence quantity. Claimants wanting faster resolution should pursue settlement actively rather than demand full hearing.

What If My Former Employer Breaches Settlement Agreement?

If settled claim via tribunal-approved settlement, you can return to tribunal to enforce breach. Tribunal can award additional compensation and costs. Alternatively, claimant can pursue breach in civil court (County Court) as breach of contract. Documented settlement (email or formal agreement) required. Claimant should ensure settlement clearly states conditions: payment amount, payment date, confidentiality terms, agreement to provide reference (if applicable). Any ambiguity can lead to disputes.

Can My Employer Retaliate Against Me for Filing Claim?

No, illegal to retaliate against employee for bringing tribunal claim. Any dismissal, demotion, pay reduction, or adverse treatment after claim filed constitutes automatic unfair dismissal plus potential victimization claim (separate offense). Employer cannot threaten claimant with retaliation. Claimants often fear retaliation but statute protects against it. If employer retaliates, claimant can add victimization claim (additional compensation). Document any retaliation immediately with dates/witnesses.

Do I Need Medical Evidence for Disability Discrimination?

Not always required but strongly advisable. Claimant must establish disability (physical or mental condition with substantial long-term adverse effect on normal daily activities). Medical report from GP or specialist supporting disability diagnosis helps prove claim. Without medical evidence, claimant must convince tribunal purely through testimony and circumstantial evidence. Employer will argue condition not disability. Medical evidence (formal diagnosis, treatment records, functional impact assessment) significantly strengthens disability discrimination claims. Claimant typically pays for medical report (£300-£1,000), though costs can be recovered from respondent if claim successful.

What if I Was Dismissed While on Sick Leave?

Dismissal while on sick leave triggers additional legal concerns. Generally unfair to dismiss during sick leave without full investigation into medical condition and exploring alternatives (e.g., flexible work, adjusted duties). Employer should obtain medical evidence, consider reasonable adjustments, and give opportunity to return. Dismissing quickly while employee ill/incapacitated may constitute unfair dismissal, disability discrimination, and procedural unfairness. If you were dismissed while sick, likely strong case exists, particularly if employer failed to investigate or consider alternatives.

Can Tribunal Order Reinstatement (Getting Job Back)?

Yes, tribunal can order reinstatement (claimant gets job back) or re-engagement (similar role with same employer). However, reinstatement rare—most claimants prefer compensation to returning hostile workplace. Employer can object to reinstatement; tribunal must consider whether practical/feasible. If employer objects and reinstatement would harm business, tribunal usually awards compensation instead. Rarely will tribunal force employer to rehire unwilling claimant. Most successful claims result in financial compensation rather than job restoration.
