Unfair dismissal and constructive dismissal, explained
Losing your job, or being pushed toward the door, is one of the most stressful things that can happen at work. This guide explains what unfair dismissal and constructive dismissal mean in England and Wales, how the law treats them, and how Zhan Associates helps you protect your position at every stage.
At a glance
Unfair vs constructive dismissal
Dismissal claims make up over half of all single claims brought to Employment Tribunals in England and Wales, which tells you how often employers get the process wrong. A dismissal is not simply the employer's decision to make. It has to be for a fair reason, and it has to be reached through a fair procedure measured against the ACAS Code of Practice on Disciplinary and Grievance Procedures. When either of those is missing, you may have grounds to challenge it.
Zhan Associates is a specialist workplace defence consultancy. We are not a firm of solicitors and we do not provide reserved legal activities or legal advice. What we provide is forensic case preparation, procedural challenge, and in-room representation as your chosen companion under Section 10 of the Employment Relations Act 1999. The sections below explain the two situations people search for most, and where we fit in.
Dismissal & Job Loss
Unfair dismissal
Unfair dismissal is where you are dismissed either without a genuinely fair reason, or without your employer following a fair procedure, or both. It is the single most searched employment law term in England and Wales, and for good reason: many dismissals that feel wrong are wrong in law too.
An employer must show that the dismissal was for one of the potentially fair reasons recognised in law, such as conduct, capability, redundancy, a legal restriction, or some other substantial reason. Even where the reason is capable of being fair, the dismissal can still be unfair if the process was not. That means proper investigation, a clear statement of the allegations, a fair hearing at which you can respond, the right to be accompanied, and a right of appeal. Where those steps are skipped or rushed, the fairness of the whole dismissal is open to challenge.
Most employees need a qualifying period of continuous employment to bring an ordinary unfair dismissal claim, though some dismissals are automatically unfair from day one, for example dismissal connected to whistleblowing, pregnancy, or asserting a statutory right. Strict time limits apply: a tribunal claim must be started within six months of the dismissal where the effective date of termination falls on or after 1 October 2026, and within three months less one day where it falls before that. Either way it is a deadline that is easy to miss and difficult to reopen.
How Zhan Associates helps with unfair dismissal
The best time to act is before the dismissal happens, while you are still in the disciplinary process and the outcome is not yet fixed. We dissect the allegations, test the evidence, benchmark the employer's procedure against the ACAS Code, and represent you in the room so your case is put with clarity and authority. Where a dismissal has already happened, we prepare and support your internal appeal, and where it goes that far, your tribunal claim.
- Early triage. A Rapid Defence Review gives you a fast, forensic read of the allegations and your realistic options.
- Full preparation. A Structured Defence Strategy builds your written defence before the hearing.
- In-room representation. Hearing representation and full hearing defence put an experienced advocate beside you.
- Appeal and tribunal. An Appeal Defence Package, or ET1 drafting through our tribunal services, where the matter proceeds.

Constructive dismissal
Constructive dismissal is where you resign because your employer has committed a serious breach of your contract, one so fundamental that you are entitled to treat the contract as at an end. In law, you are the one who resigns, but the employer's conduct is treated as having forced you out. It is one of the most searched and most misunderstood areas of employment law, because the bar is high and the steps you take before resigning matter enormously.
The breach must go to the root of the contract. Common examples include a serious unilateral cut to your pay or status, bullying or harassment that the employer fails to address, a breakdown of the implied duty of trust and confidence, or forcing through a fundamental change to your role. A series of smaller incidents can also add up to a breach, with a final act tipping the balance. Crucially, you must resign in response to the breach and without unreasonable delay: if you carry on working as normal for too long, you risk being treated as having accepted the change.
Because resigning ends your income and is difficult to undo, constructive dismissal is rarely a decision to take alone or in haste. Getting the sequence right, and preserving the evidence, is often the difference between a strong claim and a lost one.
How Zhan Associates helps with constructive dismissal
We help you assess, before you act, whether what has happened is likely to amount to a fundamental breach, and what to do to protect your position. Often the stronger route is to raise a formal grievance first and to build a documented record, rather than resign immediately. Where an exit is the right outcome, we position it on your terms.
- Assess before you resign. A Rapid Defence Review helps you understand whether the breach is likely to be fundamental, before you make an irreversible decision.
- Negotiate an exit on your terms. A Negotiation Strategy builds a without-prejudice position to leave with reference, notice and settlement terms intact.
- Conciliation and tribunal. Where needed, ACAS Early Conciliation and ET1 drafting, explained in our dispute resolution guide.
Common questions
Dismissal questions people ask
Unfair dismissal is about whether the reason for the dismissal was fair and whether a fair procedure was followed. Wrongful dismissal is a narrower, contract-based point about being dismissed without the proper notice or in breach of contract terms. Most searches and most claims concern unfair dismissal, which is judged against the ACAS Code of Practice.
Six months from the dismissal where the effective date of termination falls on or after 1 October 2026, and three months less one day where it falls before that. Either way the clock is paused while ACAS Early Conciliation takes place, and an internal appeal does not pause it. The deadline is strict and easily missed, so the earlier you take advice the more options you keep open.
For an ordinary unfair dismissal claim you normally need a qualifying period of continuous employment. However, some dismissals are automatically unfair from day one, such as those connected to whistleblowing, pregnancy, or asserting a statutory right, where no qualifying period applies.
Constructive dismissal is where your employer commits a serious breach of your contract, so fundamental that you are entitled to resign and treat the contract as at an end. The breach must go to the root of the contract, and you must resign in response to it without unreasonable delay.
Resigning ends your income and is hard to undo, so it is rarely a step to take without preparation. Often the stronger route is to raise a formal grievance first and build a documented record. We help you assess whether the breach is likely to be fundamental before you make an irreversible decision.
