    What are the time limits for making an unfair dismissal claim

    If you have been dismissed from your job and believe the dismissal was unfair, you must act quickly. Employment tribunal claims are subject to strict time limits and missing the deadline means losing your right to bring a claim entirely: regardless of how strong your case may be.

    The Basic Time Limit

    The time limit for bringing an unfair dismissal claim to an employment tribunal is three months minus one day from the effective date of termination (EDT). The EDT is usually the last day of your employment. The date your notice period expired or, if you were dismissed without notice, the date you were told your employment ended.

    This means that if your employment ended on 1 April, you must present your claim to the tribunal by 30 June at the latest. Missing this date by even a day will normally result in your claim being rejected.

    The ACAS Early Conciliation Requirement

    Before you can submit a claim to the employment tribunal, you must first contact ACAS for early conciliation. This is a mandatory step. During early conciliation, ACAS attempts to help the parties reach a settlement without going to tribunal.

    The early conciliation process pauses the time limit for the period ACAS is involved. If conciliation does not result in a settlement, ACAS issues a certificate which you must include with your tribunal claim. The time limit calculation is adjusted to account for the period of early conciliation, which means the effective deadline for your claim may be later than the basic three months minus one day.

    This is an important point: do not wait until the last few days of the three-month period before contacting ACAS. Start the early conciliation process well in advance.

    Can the Time Limit Be Extended?

    Employment tribunals have the power to extend the time limit in limited circumstances where it was "not reasonably practicable" to present the claim in time. This is a narrow test and tribunals apply it strictly. Acceptable reasons might include a genuine medical emergency that prevented you from acting, or circumstances entirely outside your control. Simple ignorance of the time limit, or delays in obtaining legal advice, are generally not accepted as sufficient reasons.

    Do not rely on the possibility of an extension. Treat the three-month period as an absolute deadline.

    What Is the Qualifying Period?

    To bring an unfair dismissal claim, you generally need at least two years of continuous employment with the same employer. This qualifying period does not apply in certain situations. For example,, if you were dismissed for a reason connected to whistleblowing, pregnancy or maternity, trade union membership, or exercising other statutory rights. In those cases, you can bring a claim regardless of how long you have worked for the employer.

    Do I Need Legal Help?

    You can represent yourself at an employment tribunal, but having a barrister represent you, particularly at the final hearing: significantly improves your ability to present your case, cross-examine witnesses, and argue legal points effectively. Through Direct Access, you can instruct a barrister without going through a solicitor first.

    Summary

    The time limit for an unfair dismissal claim is three months minus one day from your effective date of termination, subject to adjustment for the mandatory ACAS early conciliation period. The limit is applied strictly. You must also have at least two years of continuous employment in most circumstances. If in doubt, take legal advice immediately: do not let the deadline pass.
