Dismissed while on sick leave? You may have a strong claim

Being ill is not a reason to dismiss someone unfairly. Employers regularly rush dismissals during sick leave without proper medical evidence, without exploring alternatives, and without giving the employee a real chance to respond. If that happened to you, the Employment Tribunal can award compensation.

Can I be dismissed while on sick leave?

Yes, but dismissal during sick leave is subject to the same legal standards as any other dismissal. After two years of continuous employment you have full unfair dismissal protection. Your employer must have a fair reason and follow a fair procedure — simply being absent through illness is usually not enough on its own.

Is dismissal while on sick leave automatically unfair?

Not automatically, but it is frequently unfair in practice. Tribunals look at whether the employer carried out a proper investigation, obtained medical evidence, considered alternatives to dismissal, and gave you the opportunity to make representations. Skipping any of these steps can make a dismissal unfair.

Can I claim disability discrimination if dismissed on sick leave?

Yes, if your illness amounts to a disability under the Equality Act 2010 (a physical or mental impairment with a substantial and long-term adverse effect on normal day-to-day activities). Dismissing a disabled employee without making reasonable adjustments is disability discrimination — and there is no compensation cap on discrimination awards.

What if my employer replaced me while I was off sick?

Replacing someone while they are on sick leave is a significant indicator of unfair dismissal. It can suggest the decision to dismiss was made before any proper process was followed. It is also potentially disability discrimination if your absence was related to a disability.

What is the time limit to claim if dismissed on sick leave?

3 months less one day from the effective date of termination (usually your last day of employment or the date notice expired). ACAS Early Conciliation must be started before filing at the Employment Tribunal.

What makes a sick leave dismissal unfair?

Tribunals apply the general unfair dismissal test: did the employer have a potentially fair reason (capability is the most common for sickness), and did they act reasonably in treating that reason as sufficient to dismiss? In the context of long-term or repeated sickness absence, tribunals look for the following steps:

The employer must obtain proper medical evidence — usually an occupational health report or a GP/specialist letter — before deciding to dismiss. Dismissing without any medical evidence is almost always unfair.

Prognosis and return date

The employer must consider the prognosis: is there a prospect of return to work and, if so, when? If the medical evidence suggests a return within a reasonable period, dismissal may not be justified at that stage.

Exploration of alternatives

Has the employer considered phased return, adjusted duties, reduced hours, or a different role? Dismissing without exploring alternatives — especially where the employee is disabled — is a significant procedural failing.

Consultation with the employee

The employer must consult with you before dismissing — explain the situation, share the medical evidence, and give you a genuine opportunity to respond. A sham "meeting" with a dismissal letter already drafted is not proper consultation.

You must be offered a right of appeal against the decision to dismiss. Denial of an appeal right is a procedural failing that strengthens a tribunal claim.

Disability discrimination — a separate and stronger claim

If your sickness absence was caused by a condition that amounts to a

under the Equality Act 2010, you have a separate — and potentially much stronger — disability discrimination claim. A disability is a physical or mental impairment that has a substantial and long-term adverse effect on normal day-to-day activities. "Long-term" means has lasted or is likely to last 12 months or more.

Many conditions that employees do not think of as "disabilities" qualify — depression, anxiety, chronic back pain, IBS, cancer, MS, and many others. Cancer, HIV, and MS are automatically disabilities from the point of diagnosis.

No compensation cap for disability discrimination

Disability discrimination claims carry no statutory cap on compensation. Awards include financial losses and injury to feelings (Vento bands). This makes disability discrimination claims significantly more valuable than standalone unfair dismissal claims, which are subject to the compensatory award cap (£123,543 in 2026/27).
