The 2-year rule is real — but it has significant exceptions. If your dismissal was for a prohibited reason, your length of service is irrelevant.
Standard vs Automatically Unfair Dismissal
| Type | Qualifying period | Examples |

| Automatically unfair dismissal | None | Pregnancy, whistleblowing, statutory rights |
| Discrimination dismissal (Equality Act) | None | Race, sex, disability, age, religion, etc. |
| Wrongful dismissal (breach of contract) | None | Dismissed without contractual notice pay |

What If You Are Not Covered?
If you have under 2 years’ service and the reason is not automatically unfair, consider:
- Wrongful dismissal: did the employer breach your contract (e.g. not pay notice)? You can claim in Employment Tribunal or civil court
- Discrimination: was a protected characteristic involved?
- Agency worker: different rules apply in some cases
Making a Day-One Rights Claim
If you believe you were dismissed for an automatically unfair reason (even with under 2 years’ service), the process is:
- ACAS Early Conciliation — you must contact ACAS before starting a tribunal claim. Early conciliation is free and can result in a settlement without going to tribunal. ACAS will contact your employer on your behalf. The clock stops during conciliation.
- File an Employment Tribunal claim — if conciliation does not resolve the issue, you can file online at employment-tribunals.service.gov.uk. The time limit is 3 months minus one day from the date of dismissal.
- No fee to file — Employment Tribunal claims are free since 2017.
What you can claim: If successful, a day-one rights claim can result in a basic award (calculated on age and service), a compensatory award (up to £115,115 in 2025/26 — your financial losses), and in discrimination cases, an uncapped compensatory award.
Even where you do have under 2 years’ service, documenting the reason given for dismissal carefully from the outset gives you the best chance of identifying whether any automatic protection applies.
