Can I claim constructive dismissal with less than two years' service?
Short answer
Generally no — constructive dismissal is a type of unfair dismissal, so the two-year qualifying period applies. But if the conduct that forced you out amounted to discrimination, whistleblowing detriment or another automatically unfair reason, you can claim regardless of length of service.
Constructive dismissal is where your employer's conduct — a fundamental breach of your contract, typically of the implied term of trust and confidence — leaves you with no real choice but to resign. The law then treats your resignation as a dismissal. Because the claim is brought as unfair dismissal under the Employment Rights Act 1996, the usual two-year service requirement applies.
Routes that do not need two years
With shorter service, the question becomes whether the same conduct supports a different claim:
- Discrimination — if the treatment was because of a protected characteristic (sex, race, disability, pregnancy and so on), you can claim under the Equality Act 2010 from day one. A role downgraded after maternity leave, for example, can be both a fundamental breach and maternity discrimination.
- Whistleblowing detriment or dismissal — no qualifying period applies if you were forced out after making a protected disclosure.
- Asserting a statutory right — resignation forced by retaliation for claiming minimum wage or other statutory rights can also be automatically unfair with no service requirement.
Documenting events carefully from the outset — timestamped emails, diary notes, witness names — preserves your options whichever route ultimately applies.
If you are thinking of resigning
Constructive dismissal claims are high-risk even with long service: you give up your income immediately, and you must prove a fundamental breach (not just unreasonable behaviour), that you resigned in response to it, and that you did not delay so long that you affirmed the contract — usually a matter of weeks from the last incident. Before resigning:
- Raise a formal grievance — not legally required, but failing to do so can cut any award by up to 25%, and it creates key evidence
- Take advice from Acas or an employment solicitor on whether the breach is strong enough
- If you do resign, say clearly in your letter that you are resigning because of the employer's breach
The deadline is three months less one day from resignation to start Acas Early Conciliation — and many of these cases settle at that stage.
