Constructive Dismissal: When Resigning Counts as Dismissal

What constructive dismissal actually means

Constructive dismissal is not a separate claim you tick on the ET1. It is a route to an unfair dismissalclaim where you resigned instead of being dismissed. The Employment Rights Act 1996 section 95(1)(c) treats a resignation as a dismissal where the employee is entitled to end the contract, without notice, because of the employer’s conduct.

Because you chose to leave, the burden is on you to show the employer’s conduct justified it. That is why constructive dismissal is one of the harder positions to run, and why organising the facts carefully matters.

The three-part test

1. Fundamental breach.The employer committed a serious (repudiatory) breach going to the root of the contract, or a series of acts whose “last straw” crossed that line. A common basis is breach of the implied term of mutual trust and confidence.
2. Resignation in response. You resigned because of that breach, not for an unrelated reason.
3. No affirmation. You did not accept the breach and carry on as normal for too long. Delay can be read as affirming the contract.

Conduct that is often argued as a fundamental breach

• An unlawful cut to pay or a unilateral, unagreed change to core terms.
• An unjustified demotion or removal of significant duties.
• Serious bullying or harassment, or a failure to protect you from it.
• A failure to deal with a serious, properly-raised grievance.
• Requiring unsafe work, or a serious breach of health and safety duties.

A single minor issue is unlikely to be enough. A pattern can be, if a final act tips it over.

Before you resign

Resigning is the highest-risk step in an employment dispute. As a practical matter, most people are advised to raise a formal grievance first and give the employer a chance to put things right. That both tests the position and creates a record. This guide does not tell you whether to resign — that is a decision to take with proper advice.

Facts to organise for the ET1 narrative

• Employment start date, resignation date, and notice position.
• The specific term or duty you say was breached.
• The events, in date order, that make up the breach or the last straw.
• The grievance you raised, when, and how the employer responded.
• Why you resigned when you did (to answer any “affirmation” argument).
• Losses: lost wages, notice pay, pension, benefits, job-search evidence, and new earnings.

Time limits and ACAS

Before an ET1 you must notify ACAS for early conciliation, and tribunal claims are generally subject to a three-month-less-one-day limit from the effective date of termination. See ACAS and time limits for how the clock and the conciliation step interact.
