What is constructive dismissal? Signs you were forced out

Constructive dismissal is what happens when you resign because your employer's behaviour has made staying impossible. In law you are treated as having been dismissed, even though you were the one who handed in notice. It is also one of the hardest claims to win, which is why the order in which you do things matters so much.

The legal test

You have to show three things.

• A repudiatory breach of contract by your employer. Not merely unreasonable or unfair behaviour, but a serious breach that goes to the root of the contract.
• That you resigned because of that breach. It does not have to be the only reason, but it must be a genuine reason for going.
• That you did not delay. Stay too long after the breach and you are treated as having accepted it, which destroys the claim.

What counts as a serious breach

Some breaches are obvious: cutting your pay, demoting you, unilaterally changing your hours or place of work, or removing your duties without any contractual right to do so.

Most claims instead rely on the implied term of trust and confidence, which every employment contract contains. Your employer must not, without proper cause, behave in a way likely to destroy or seriously damage the relationship of trust and confidence between you.

Examples that have succeeded include sustained bullying or harassment, failing to deal with a serious grievance, false accusations of misconduct, humiliating someone in front of colleagues, failing to protect an employee from harassment by others, and imposing an unjustified disciplinary sanction.

Examples that generally do not succeed on their own include a single rude comment, a manager you dislike, a fair performance process you disagree with, or a reasonable management instruction you would rather not follow.

The last straw

A breach can be built from a series of incidents rather than one event. Where a course of conduct culminates in a final act, you can resign in response to the whole of it, even if the final act on its own is relatively minor.

The final act must still contribute something to the breach. A genuinely innocuous event does not revive earlier incidents you had already accepted and moved past.

Timing, and the mistake most people make

Resigning quickly is often necessary to preserve the claim, but resigning in anger before taking advice is the most common way good claims are lost.

Two points are worth understanding. First, the delay that kills a claim is measured from the breach, and there is no fixed number of weeks. Working on for months without protest is usually fatal. Continuing to work while making clear in writing that you are working under protest, and while a grievance is being heard, is usually not.

Second, you do not have to resign at all. If you can stay, raise a grievance and let it run, you keep your income and your options while your employer either fixes the problem or makes your case stronger.

Grievances, notice and evidence

Raise a grievance in writing before you go, if you possibly can. It is not a strict legal requirement, but a tribunal can reduce compensation by up to 25% where an employee unreasonably fails to follow the ACAS Code, and the grievance is often the document that proves the breach and your objection to it.

Resign in writing, and say clearly that you are resigning because of your employer's conduct, referring to the specific matters. A bland resignation letter thanking everyone for a wonderful few years is a gift to the other side.

Think about notice. Where the breach is serious you may be entitled to resign without notice, and doing so signals that you treated the breach as fundamental. Working full notice can be argued as affirming the contract, so this is a point to take advice on rather than guess.

What it is worth

If you win, remedies mirror unfair dismissal: a basic award and a compensatory award for your losses, subject to the statutory cap, which is reviewed each April, and to the usual reductions for contributory conduct or the chance you would have left anyway.

If the underlying conduct also amounts to discrimination or a detriment for whistleblowing, the picture changes substantially, because those claims are not capped in the same way and can include an award for injury to feelings. Many constructive dismissal cases are really discrimination cases in disguise, which is exactly the assessment a specialist can make quickly.

The same three-month less one day deadline applies, running from the date your resignation takes effect, with the clock paused while ACAS early conciliation runs.

Before you resign

Speak to a specialist employment solicitor first, ideally the same week. The advice is usually practical rather than dramatic: what to put in the grievance, whether to go now or wait, what to say in the resignation letter, and what the claim is realistically worth. Those decisions, taken in the right order, are usually worth more than anything that can be done afterwards.
