Unfair Dismissal In The UK: What Employees Need To Know

Most employees in England and Wales need two years of continuous service before they can claim ordinary unfair dismissal, although automatically unfair reasons — whistleblowing, pregnancy, asserting a statutory right — have no qualifying period.

The time limit is strict: a claim must be lodged with the employment tribunal within three months less one day of the effective date of termination, after first notifying ACAS for early conciliation, which pauses the clock.

Employers often offer a settlement agreement in exchange for waiving claims. You must receive independent legal advice on the terms for the agreement to be valid, and the employer usually contributes to that advice.

Compensation consists of a basic award (calculated like statutory redundancy pay) and a compensatory award capped at the lower of a year's gross pay or the statutory limit, unless the dismissal is discriminatory or whistleblowing-related.

Keep every document: the dismissal letter, appeal outcome, contract, handbook and any messages about performance. They shape both the merits and the negotiation.
