Unfair Dismissal Response Checklist

If you believe your dismissal was unfair, the order in which you act matters as much as what you do. There is a strict time limit for starting a tribunal claim, it does not pause while you pursue an internal appeal, and evidence becomes harder to obtain once you no longer have access to work systems. Acting in the first few days protects options you cannot recover later. Use this checklist to make sure you do not miss a step or a deadline while you are still absorbing the news.

The deadline comes before everything else

Most employment tribunal claims must begin with Acas early conciliation within three months less one day of the dismissal. That deadline does not pause while you run an internal appeal, and tribunals extend it only in narrow circumstances. Notify Acas early — it stops the clock while conciliation runs, costs nothing, and does not commit you to bringing a claim. Treat the internal appeal and the Acas notification as parallel tracks rather than one after the other.

  • Immediately: ask for the dismissal reasons in writing, gather your contract, handbook, payslips and any relevant messages, and write down a dated account while it is fresh.
  • Within days: lodge the internal appeal if there is one, and notify Acas.
  • Throughout: keep applying for work. Compensation for unfair dismissal is reduced if you have not taken reasonable steps to mitigate your loss, so keep a record of applications.

Do not sign a settlement agreement before taking independent advice — the agreement is not binding without it, and employers usually contribute to the cost. Check what is genuinely on offer beyond your notice pay, accrued holiday and any redundancy entitlement, which are owed anyway.

Access to your own records helps. A subject access request obliges your employer to provide the personal data it holds about you, which often includes internal emails and meeting notes about the decision.

Frequently asked questions

Do I need two years' service to bring a claim?
For ordinary unfair dismissal, generally yes. But several claims need no minimum service at all: discrimination connected to a protected characteristic, dismissal for whistleblowing, dismissal for asserting a statutory right, and dismissal connected to pregnancy or family leave, among others. If any of those might apply, do not assume you are out of time or out of options because you were there less than two years. Get advice quickly, because the same short deadline applies.
What can I actually recover if I win?
Unfair dismissal awards usually combine a basic award, calculated like redundancy pay from your age, service and weekly pay, with a compensatory award for financial loss, which is subject to a statutory cap. Discrimination awards are uncapped and can include compensation for injury to feelings. Awards are reduced where you failed to mitigate your loss or contributed to the dismissal, and reinstatement is possible but rare. Keep evidence of earnings lost and jobs applied for.
Should I still appeal internally if I intend to bring a claim?
Yes, in almost all cases. Employers sometimes overturn dismissals at appeal, and an appeal often produces documents and explanations you would not otherwise see. A tribunal can also reduce compensation where an employee unreasonably failed to use an internal appeal. Keep the appeal factual and specific about what went wrong in the process. Just do not let it consume your time limit — notify Acas regardless of where the appeal has got to.
What if I resigned rather than being dismissed?
You may still have a claim for constructive dismissal, where the employer's conduct amounted to a fundamental breach of contract and you resigned in response without delay. These claims are harder to win than ordinary unfair dismissal, and waiting too long before resigning can be treated as accepting the conduct. Raise a grievance first if you can, resign promptly and state the reasons clearly in writing, and take advice before you go if there is any opportunity to do so.
