Constructive dismissal is the claim you build before you resign — not after. If your employer's conduct is forcing you out, the steps you take in the next weeks decide whether you leave with a claim or just a resignation letter. Connaught Law's employment solicitors advise employees across London and the UK at exactly this point, when it still counts.

How We Can Help
What Counts as Constructive Dismissal
Constructive dismissal is resignation treated in law as a dismissal, because your employer fundamentally broke the employment contract first — an express term like pay, or the implied duty of trust and confidence every contract contains. The breach must be serious, not a minor grievance; a course of conduct counts, where a final "last straw" incident caps a pattern that made staying untenable. Resign in response to a breach like that and you can claim as though you'd been sacked.
Situations That Qualify
The common patterns: pay or commission cut or withheld, demotion or duties stripped without agreement, forced relocation, bullying or harassment that management ignored, disciplinary action used oppressively, and being required to work in unsafe conditions. One serious incident can be enough; more often it's the accumulation that crosses the line — which is why the timing of your response matters so much.
Before You Resign — Get Advice First
This claim is won or lost before the resignation letter. Delay too long after the breach and you may be taken to have accepted it; resign too fast, without raising a grievance, and a tribunal may cut your award for skipping the ACAS Code steps. The sequence — grievance, response, resignation with reasons stated — needs to be right. Thirty minutes of advice before you resign is worth more than thirty hours after.
How to Claim
Constructive dismissal is a form of unfair dismissal under the Employment Rights Act 1996, so the ordinary claim currently requires two years' service — with the same exceptions as any dismissal, and a parallel breach-of-contract claim for notice pay that needs no qualifying period. The route: ACAS early conciliation, then a tribunal claim within three months less one day of your resignation taking effect. Our unfair dismissal service covers the tribunal process in full.
Compensation & Awards
Succeed and the award works like any unfair dismissal: a basic award from your age, pay and service, plus a compensatory award for lost earnings and benefits while you find comparable work — capped by statute unless discrimination or whistleblowing is involved, and adjustable up or down for how each side handled the grievance process. Our employment tribunal awards guide sets out the current figures and how tribunals actually calculate them.
Building the Evidence
Tribunals decide these cases on the record: the contract, the grievance and its response, emails and messages showing what changed, notes of meetings made at the time, and medical evidence where the treatment affected your health. We help you build that record while you're still employed — quietly and lawfully — so that if resignation becomes the only option, the claim behind it is already made.
How We Work
We start with the question that decides everything: is the breach serious enough, and is it still live? From there we plan the sequence — grievance wording, timing, the resignation letter itself — and assess what the claim is realistically worth, because many constructive dismissal situations resolve best as negotiated exits with a settlement agreement rather than tribunal claims.
If you've already resigned, move immediately: the three-month clock started the day your employment ended, paused only by ACAS early conciliation. Bring your contract, grievance correspondence and timeline to the first call and we'll tell you where you stand the same week.

Frequently Asked Questions
What is constructive dismissal?
Resignation forced by your employer's fundamental breach of contract — withheld pay, demotion without agreement, or conduct destroying trust and confidence — which the law then treats as a dismissal. You claim as though you were sacked, provided you resigned in response to the breach rather than accepting it.
Should I resign before getting legal advice?
No. Resigning is the one step you can't take back, and both the timing and the wording of your resignation affect the claim. Take advice first — ideally before raising the grievance — so the sequence protects your position. If you've already resigned, get advice immediately: the three-month clock is running.
How long do I have to claim constructive dismissal?
Three months less one day from the date your employment ended, with mandatory ACAS early conciliation pausing the clock while it runs. Tribunals rarely extend this limit — treat it as absolute.
How much compensation do you get for constructive dismissal?
The same structure as unfair dismissal: a basic award based on age, pay and service, plus compensation for lost earnings while you find comparable work — statutorily capped unless discrimination or whistleblowing is involved. The realistic value depends heavily on how quickly you're likely to be re-employed; we value your claim honestly before you decide anything.
Being pushed out?
Don't resign yet. Tell us what's happening and we'll map the safest sequence — grievance, evidence, exit — so you leave with a claim or a settlement, not just a resignation.
