Constructive dismissal occurs when your employer's behaviour forces you to resign. This guide explains what counts, how to prove it, and how to make a tribunal claim — in plain English.
If your employer has made your working life intolerable — cutting your pay, changing your role without consent, or allowing harassment to go unchecked — and you feel you have no choice but to resign, you may have a claim for constructive dismissal.
This is one of the most misunderstood areas of UK employment law. This guide explains what it is, when it applies, and how to claim.
Constructive dismissal occurs when an employee resigns because their employer has fundamentally breached the employment contract. The law treats this as a dismissal by the employer, even though the employee technically resigned.
The key concept is the "implied term of mutual trust and confidence" — an obligation that runs through every employment contract. If your employer's conduct is so serious that it destroys this trust, you can treat the contract as ended by them.
The legal test comes from the Employment Rights Act 1996, s.95(1)(c): you are dismissed if you terminate your contract "in circumstances in which you are entitled to terminate it without notice by reason of the employer's conduct."
Not every bad management decision amounts to constructive dismissal. The breach must be fundamental — that is, it must go to the heart of the contract.
Examples that courts have upheld as constructive dismissal:
What does NOT amount to constructive dismissal (usually):
You do not necessarily need a single dramatic event. A series of individually minor incidents can collectively amount to a fundamental breach — if the cumulative effect destroys trust and confidence.
The final incident (the "last straw") does not need to be serious in itself, but it must be related to the employer's earlier conduct and can tip the balance if the background is already serious enough.
This is where many constructive dismissal claims fail.
If you continue working for a significant period after the fundamental breach, you may be seen to have affirmed (accepted) the breach, and lose your right to claim. There is no absolute time limit, but:
You should always resign in writing, clearly stating that you are resigning in response to the employer's conduct. Keep a copy.
To bring a standard unfair dismissal claim (including constructive dismissal), you need 2 years' continuous service with your employer.
Exceptions — no qualifying period needed if your constructive dismissal is related to:
If you have less than 2 years' service but the breach relates to one of these areas, you can still claim.
Before resigning, you should strongly consider raising a formal grievance with your employer. There are two reasons:
Raising a grievance also helps evidence that you took the matter seriously before resigning.
Before making a tribunal claim, you must first contact ACAS for Early Conciliation. This is a free, confidential service that attempts to resolve the dispute before it reaches a tribunal. You have a one-month period to attempt conciliation.
If Early Conciliation fails, you can submit your claim to the Employment Tribunal. The time limit is strict:
You must submit your ET1 claim form via the Employment Tribunal online portal.
If your constructive dismissal claim succeeds at tribunal, you may be awarded:
| Component | Details |
|---|---|
| Basic award | Calculated like statutory redundancy pay — based on age, service, and weekly pay (capped at £719) |
| Compensatory award | Your financial losses from losing the job — subject to a cap of the lower of £115,115 or 52 weeks' pay |
| Uplift | Up to 25% more if the employer failed to follow the ACAS Code |
| Injury to feelings | If the dismissal involved discrimination |
