What is constructive dismissal under UK employment law?
Constructive dismissal occurs when an employer commits a fundamental breach of the employment contract and the employee resigns in response to that breach. The employee has not been dismissed but treats themselves as having been dismissed. The right to claim constructive unfair dismissal is found in the Employment Rights Act 1996.
Do I need two years of service to bring a constructive dismissal claim?
Yes. To bring an ordinary constructive unfair dismissal claim you need two years of continuous employment with the same employer. There is no qualifying period if the reason for your resignation relates to automatically unfair reasons such as whistleblowing, pregnancy, or assertion of a statutory right.
What are common examples of a fundamental breach that could support a constructive dismissal claim?
Common examples include a unilateral cut in pay or hours, a serious and sustained campaign of bullying or harassment, a unilateral change to your role or duties without agreement, failing to address a grievance about serious misconduct by a colleague, and making the working environment intolerable through humiliation or marginalisation.
Must I raise a formal grievance before resigning?
You are not legally required to raise a grievance before resigning, but failing to do so will likely reduce any compensation awarded by up to 25 per cent under the ACAS Code of Practice on Disciplinary and Grievance Procedures. Raising a grievance also demonstrates that you attempted to resolve the issue internally before treating the contract as terminated.
How should I resign to preserve a constructive dismissal claim?
Resign in writing, stating clearly that you are resigning because of the employer's fundamental breach of contract and that you accept the breach as bringing the contract to an end. Do not delay after the breach — resigning too long after the breach can amount to affirming the contract and losing your right to claim.
What is ACAS Early Conciliation and when must it happen?
Before submitting an ET1 claim form to the Employment Tribunal you must contact ACAS and notify them of your intention to bring a claim. ACAS will offer a free Early Conciliation period of up to six weeks during which a conciliator will attempt to help the parties reach a settlement. The time limit for your ET1 claim is paused during the Early Conciliation period.
What is the time limit for a constructive dismissal ET1 claim?
You must contact ACAS within three months less one day of your last day of employment (the effective date of termination). Missing this deadline will almost certainly mean your claim is rejected. The Tribunal can extend the deadline only where it was not reasonably practicable to bring the claim in time.
How is constructive dismissal compensation calculated at the Employment Tribunal?
Compensation has two elements. The basic award is calculated in the same way as a statutory redundancy payment: based on age, length of service, and weekly pay (capped at the statutory weekly pay cap). The compensatory award covers actual financial loss — lost earnings, lost benefits, and future loss — subject to a cap of one year's gross pay or the statutory maximum, whichever is lower.
Can I represent myself at the Employment Tribunal for a constructive dismissal case?
Yes. Employment Tribunal proceedings are designed to be accessible to litigants in person. There are no court fees for employment claims. You can submit your ET1 online at employment.tribunals.gov.uk and attend the hearing without legal representation, though complex cases with multiple witnesses benefit from preparation.
