Constructive Dismissal Explained
A plain English guide to constructive dismissal, when employees can resign and claim unfair dismissal, and how Employment Tribunals assess these cases.
Constructive dismissal happens when an employer's serious misconduct forces an employee to resign. Simply being unhappy at work isn't enough — the law requires a fundamental breach of contract and a prompt resignation in response. CaseIntel compares your situation against real Employment Tribunal decisions.
What is constructive dismissal?
Constructive dismissal is a form of dismissal where the employee, not the employer, ends the employment — but the law treats it as if the employer had dismissed them. It happens when an employer's conduct is so serious that the employee is entitled to resign and treat the contract as at an end.
Three elements have to line up:
A fundamental breach
The employer has done something — or failed to do something — that goes to the root of the employment contract.
A resignation in response
The employee resigns because of that breach, not for an unrelated reason.
No delay or acceptance
The employee acts reasonably promptly. Carrying on as normal can be treated as accepting the breach.
When can you claim?
To bring a constructive unfair dismissal claim in an Employment Tribunal, the situation usually has to satisfy each of the following.
Fundamental breach
The employer's conduct must amount to a serious breach of contract — not just unreasonable behaviour or a one-off bad day.
Resignation in response
You must resign because of the breach. If you'd already decided to leave for another job, that link is much harder to show.
Act promptly
Long delays — or continuing to work as if nothing happened — can be treated as 'affirming' the contract and waiving the breach.
Qualifying service
Constructive unfair dismissal claims usually require around two years' continuous service. Discrimination-based claims do not have this threshold.
Fundamental breach of contract
A fundamental breach is one that goes to the heart of the employment relationship. Every employment contract contains an implied term of mutual trust and confidence — a duty on the employer not to behave in a way calculated or likely to destroy that relationship. Many constructive dismissal claims turn on this implied term.
Non-payment of wages
Withholding salary, refusing to pay agreed bonuses, or unilaterally cutting pay can amount to a fundamental breach.
Bullying or harassment
A pattern of serious bullying, harassment or victimisation — particularly where the employer fails to address it — can destroy trust and confidence.
Unilateral pay cuts
Cutting pay, bonuses or significant benefits without agreement is a classic example of fundamental breach.
Major changes to duties
Forcing a fundamentally different role on someone — far beyond what the contract or any flexibility clause allows — can be a breach.
Unsafe working conditions
Ignoring serious health and safety risks, or requiring work in conditions that endanger the employee.
Breach of trust and confidence
Conduct without reasonable and proper cause that is likely to destroy or seriously damage the working relationship.
Common constructive dismissal examples
The same conduct can be fundamental in one set of circumstances and a minor irritation in another. Tribunals decide each case on its own facts, including the contract terms, the surrounding context and how the employer responded when the employee raised concerns.
Salary reduced without agreement
An employer cuts pay, bonus or benefits without the employee's consent and without any contractual right to do so.
Forced relocation
The employee is required to move to a different location well beyond what their contract or any mobility clause allows.
Harassment ignored
Serious bullying, harassment or discrimination is reported through a grievance and the employer fails to investigate or act.
Disciplinary process abused
A disciplinary or performance process is used in bad faith to push the employee out rather than to address a genuine concern.
Impossible working conditions
Workload, expectations or behaviour from management are escalated to a level that no reasonable employee could be expected to endure.
Demotion without justification
The employee is stripped of responsibilities, status or reporting lines without contractual basis or proper process.
Constructive dismissal compensation
A successful constructive unfair dismissal claim is compensated in the same way as a straightforward unfair dismissal. There are two main heads of award, plus separate rules for discrimination-based losses where they apply.
Basic Award
Calculated by reference to age, length of service and a capped weekly pay figure — broadly mirroring statutory redundancy pay.
Compensatory Award
Reflects actual financial losses flowing from the dismissal — loss of earnings, pension, benefits and the cost of finding new work, subject to a statutory cap in most cases.
Mitigation
Claimants are expected to take reasonable steps to find new work. Failing to do so can reduce the Compensatory Award.
Why awards differ
Salary, length of service, age, how quickly the employee finds replacement work, and the strength of any related discrimination claim all drive variation.
Don't sign a settlement offer without benchmarking it
Many constructive dismissal disputes resolve through a settlement agreement before tribunal. The right number depends on how strong the claim is and what comparable tribunals have actually awarded. Our Settlement Offer Checker shows you where any offer sits against real awards in similar cases.
The tribunal process
A constructive dismissal claim runs through the same Employment Tribunal process as any other unfair dismissal claim, with the same strict time limits.
ACAS Early Conciliation
Before issuing a claim you must notify ACAS, who offer a free conciliation period to try and resolve matters without a tribunal.
Submitting a claim
An ET1 claim form sets out the facts and the legal basis. Strict time limits apply — usually three months less one day from the effective date of termination.
Evidence
Constructive dismissal cases are won and lost on evidence — emails, grievance correspondence, contemporaneous notes and witness accounts of the conduct relied on.
The hearing
A tribunal panel hears evidence on whether there was a fundamental breach, whether the resignation was in response to it, and whether any award should follow.

Frequently Asked Questions
What counts as constructive dismissal?+
Constructive dismissal requires a fundamental breach of the employment contract by the employer, a resignation in response to that breach, and no significant delay before resigning.
Examples include serious unilateral pay cuts, ignored harassment, fundamental changes to a role, or a sustained course of conduct that destroys the relationship of trust and confidence.
Can I resign immediately?+
If you intend to claim constructive dismissal, you generally need to resign reasonably promptly after the breach so the employer cannot argue you accepted it by carrying on as normal.
That doesn't always mean walking out the same day — short delays to take advice or raise a final grievance are usually fine — but long delays significantly weaken the claim.
How difficult are constructive dismissal claims?+
They are widely regarded as harder to win than ordinary unfair dismissal claims because the employee has to prove the breach, the link between the breach and the resignation, and that they didn't waive the breach.
Strong evidence — emails, grievances, witnesses, contemporaneous notes — makes a significant difference. Benchmarking the strength of the claim before resigning is critical.
Can I claim compensation?+
Yes. A successful constructive unfair dismissal claim attracts a Basic Award and a Compensatory Award in the same way as ordinary unfair dismissal, plus separate awards for any successful discrimination claim.
Awards depend on salary, length of service, age, how quickly you find new work and any related discrimination findings.
Do I need two years' service?+
Constructive unfair dismissal claims usually require around two years' continuous service, the same threshold as ordinary unfair dismissal.
Claims based on discrimination — for example where the conduct that forced the resignation relates to a protected characteristic — do not have a minimum service requirement.
Should I raise a grievance first?+
It is almost always advisable. A grievance gives the employer a chance to address the conduct, creates a clear written record, and supports any later argument that you didn't accept the breach.
Failing to raise issues internally can also reduce any later tribunal compensation through an ACAS Code uplift or reduction.
What is the time limit for bringing a claim?+
Most constructive dismissal claims must be started within three months less one day of the effective date of termination — usually the date the resignation takes effect — subject to extension via ACAS Early Conciliation.
These time limits are strict, so don't delay if you're considering a claim.
Should I try to settle instead of going to tribunal?+
Many constructive dismissal disputes resolve through a settlement agreement, often without ever reaching a final hearing.
Whether to accept, negotiate or push to tribunal depends on the strength of the claim and what's on the table — which is why benchmarking the offer against comparable awards matters.
