What is Unfair Dismissal?
Unfair dismissal is when an employer terminates your contract without a fair reason or reasonable procedure, per the Employment Rights Act 1996.
In UK employment law, your right not to be unfairly dismissed is protected under section 94 of the Employment Rights Act 1996. A dismissal is unfair unless the employer proves a fair reason from five potential categories: capability or conduct, redundancy, legal restrictions preventing continued employment, or some other substantial reason. Even with a potentially fair reason, the employer must act reasonably in treating that as grounds for dismissal, including following a fair procedure like investigations and hearings.
Tribunals assess both the reason (substantive fairness) and procedure (procedural fairness).
Do You Qualify? Understanding Qualifying Service
You generally need two years of continuous employment to claim ordinary unfair dismissal, calculated up to the effective date of termination.
Section 108 of the Employment Rights Act 1996 sets a two-year qualifying service requirement for most unfair dismissal claims. This continuous service must run until your effective date of termination (EDT), which is the last day of employment or end of notice if served. Breaks in service under 52 weeks for certain family reasons do not reset the clock.
Exceptions exist for automatically unfair reasons where no service is needed, but for standard cases like misconduct or poor performance, hit this milestone first. Calculate by checking payslips, P45, and contract start date.
Use your P60s or employer records to confirm exact start date and any breaks.
Automatic Unfair Dismissal: No Service Needed
Certain dismissals are automatically unfair regardless of service length, such as for asserting statutory rights or whistleblowing.
Under sections 98B to 104E of the Employment Rights Act 1996, dismissals for reasons like pregnancy, whistleblowing (protected disclosures), health and safety concerns, or refusing Sunday work are automatically unfair. No two-year service is required, and tribunals award higher compensation without capping uplift for procedural flaws.
Real-world example: If sacked shortly after raising minimum wage issues, this qualifies without service threshold. Identify if your dismissal links directly to a protected act.
- Whistleblowing (s103A)
- Family reasons like maternity (s99)
- Health and safety (s100)
- Trade union activities (s103)
These claims still have strict three-month time limits.
Time Limits: 3 Months and ACAS Early Conciliation
Claims must start within three months of your effective date of termination, but ACAS early conciliation pauses the clock.
Section 111(2) of the Employment Rights Act 1996 mandates presenting your claim before the end of three months beginning with the EDT. For instance, if EDT is 1 June, deadline is 31 August. Tribunals rarely extend unless not reasonably practicable.
ACAS early conciliation stops time running from the day after contact until certificate receipt (s207B ERA 1996). Early contact maximises your window; failure exhausts it without extension.
- Contact ACAS for early conciliation immediately.
- Receive certificate if no resolution.
- Submit tribunal claim using certificate number within remaining time.
Missing the limit bars your claim permanently.
Building Your Unfair Dismissal Claim
Gather evidence of unfair reason or procedure flaws, like lack of warnings or biased investigations.
Strengthen your case by documenting grievances, emails showing inconsistent treatment, and witness statements. Compare your dismissal to similar cases where colleagues kept jobs. Highlight procedural gaps, such as no disciplinary hearing or appeal opportunity, breaching ACAS code.
Self-representers succeed by organising chronology: timeline of events, employer responses, and impact on you.
- Employment contract and handbook
- Dismissal letter
- Meeting notes and emails
- Witness contacts
Create a dated timeline first.
The Employment Tribunal Process
After ACAS, submit ET1 form online, exchange bundles, attend preliminary and final hearings.
Use the ACAS certificate to file your claim via gov.uk employment tribunal portal. Respondent contests with ET3; case management orders follow for witness statements and bundle preparation. Most settle at preliminary hearing; full merits hearing tests evidence.
Represent yourself by practising direct questions and sticking to facts; tribunals assist lay people.
- File ET1 within time limit.
- Prepare bundle and statements.
- Attend case management discussion (CMD).
- Present at final hearing.
Tribunals are free to claim; no fees.
Remedies: Compensation and More
Successful claimants get basic award (redundancy-like), compensatory award up to £115,115 (2024 limit), or reinstatement.
Remedies under ss112-128 ERA 1996 include basic award (age/service based, max £700/week), compensatory (losses like earnings, capped at £115,115 or 52 weeks gross), and rare re-engagement orders. Uplifts apply for ACAS code breaches (+25%).
Calculate potential: basic mirrors redundancy; compensatory covers net losses mitigated by job search.
One-year gross pay alternative cap if higher.
