Do I need 2 years' service to claim unfair dismissal?

Generally yes. Under the Employment Rights Act 1996, you must have at least 2 years' continuous service with your employer to bring a standard unfair dismissal claim. However, there are important exceptions where no qualifying period is needed — these are known as 'automatically unfair' reasons for dismissal.

What are the exceptions to the 2-year rule?

No qualifying period is needed if you are dismissed for: asserting a statutory right, whistleblowing, pregnancy or maternity-related reasons, trade union membership or activities, health and safety activities, working time or minimum wage rights, making a flexible working request, or discrimination under the Equality Act 2010 (which is a separate type of claim).

How is continuous service calculated?

Continuous service starts on your first day of employment. Gaps of up to one week (Sunday to Saturday) between contracts with the same employer do not break continuity. Periods of sickness, maternity leave, paternity leave, annual leave, and temporary lay-offs all count towards continuous service. If you are transferred under TUPE, your service with the previous employer counts.

What if I have less than 2 years' service — can I claim anything?

Even with less than 2 years' service, you may still have claims for: wrongful dismissal (if the employer failed to give proper notice), discrimination under the Equality Act 2010 (which has no qualifying period), automatically unfair dismissal reasons, unpaid wages or holiday pay, or breach of contract. You should always check whether any of these apply.

What is the time limit for an unfair dismissal claim?

You must start ACAS Early Conciliation within 3 months less one day of the date your employment ended (the effective date of termination). After conciliation, you then have at least one month to file your claim with the employment tribunal. These time limits are strictly enforced and missing them can mean losing your right to claim.

Unfair Dismissal: The 2-Year Qualifying Period Explained 2026

To bring a standard unfair dismissal claim in the UK, you generally need at least 2 years of continuous employment. This is one of the most important gateways to understand — if you have been dismissed and have less than 2 years' service, a standard unfair dismissal claim may not be available to you. However, there are significant exceptions where no qualifying period is needed, and you may still have other types of claims even with short service. Here is everything you need to know.

The 2-Year Rule

Under section 108 of the Employment Rights Act 1996, an employee must have been continuously employed for a period of not less than 2 years ending with the effective date of termination to bring a claim for ordinary unfair dismissal. This rule was introduced in 2012 (increased from 1 year) and remains in force as of 2026.

The "effective date of termination" (EDT) is generally the last day of your employment — or the last day of your notice period if you worked your notice. Calculating this date correctly is critical because both the 2-year qualifying period and the 3-month time limit are measured from the EDT.

Step-by-Step: How to Work Out If You Qualify

Calculate your continuous service. Count from your first day of employment to your effective date of termination. Include weeks where you did not work but were still employed — for example, periods of sickness absence (including statutory sick pay periods), annual leave, maternity/paternity/shared parental leave, and adoption leave all count. Even if you were on a zero-hours contract, weeks where you worked at least once count as continuous service, and gaps of up to one week may not break continuity.
Check for breaks in service. A gap of more than one complete week (Sunday to Saturday) between employments with the same employer will generally break continuity. However, certain absences are preserved by statute — for example, a gap caused by a "temporary cessation of work" or by "arrangement or custom" may not break continuity. If you were dismissed and re-engaged shortly after, the gap may be bridged.
Check if TUPE applies. If your employment transferred under the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE), your service with the previous employer counts towards the 2-year period with the new employer. You should have been informed about this at the time of the transfer.
If you have less than 2 years, check the exceptions. See the list below — many common dismissal scenarios do not require 2 years' service.

Exceptions: When You Do NOT Need 2 Years' Service

The following dismissals are "automatically unfair" and can be claimed regardless of length of service:

Asserting a statutory right — for example, asking for minimum wage, rest breaks, or holiday pay
Whistleblowing — making a protected disclosure about wrongdoing in the workplace
Pregnancy, maternity, paternity, or adoption leave — any dismissal related to these is automatically unfair
Trade union membership or activities — including participating in lawful industrial action (subject to certain conditions)
Health and safety activities — such as being a health and safety representative or raising safety concerns
Working Time Regulations rights — refusing to exceed the 48-hour working week (unless you have opted out)
National Minimum Wage rights — complaining about being paid below the minimum wage
Making a flexible working request — although the remedy may be limited if the request was handled improperly rather than being the sole reason for dismissal
Trustee of an occupational pension scheme — performing trustee duties
Jury service — being dismissed for attending jury service

Additionally, claims under the Equality Act 2010 (discrimination, harassment, victimisation related to protected characteristics) do not require any qualifying period. These are separate from unfair dismissal claims and can be brought from day one of employment.

What If You Were Dismissed Just Before the 2-Year Mark?

This is a common tactic — employers dismissing staff at 1 year and 11 months to avoid unfair dismissal rights. If the EDT falls even one day before the 2-year anniversary, you do not meet the qualifying period for standard unfair dismissal. However, if the reason for dismissal falls within one of the automatic unfairness categories, the qualifying period does not apply. If you suspect the dismissal was discriminatory (for example, related to age, race, sex, or disability), you may have an Equality Act claim instead.

Other Claims Without 2 Years' Service

Wrongful dismissal: This is a breach of contract claim — if your employer dismissed you without giving the notice required by your contract (or statutory minimum notice), you can claim notice pay. No qualifying period is needed.
Unpaid wages or holiday pay: Claims for unpaid wages, overtime, commission, or accrued holiday pay can be brought regardless of length of service.
Breach of contract: Claims for up to £25,000 can be brought in the employment tribunal.

Jurisdiction: Great Britain

The 2-year qualifying period applies in England, Wales, and Scotland. In Northern Ireland, the qualifying period is 1 year under the Employment Rights (Northern Ireland) Order 1996. Always check the correct jurisdiction for your employment.

FAQ

Does the 2-year period include probation?

Yes. Your probation period counts towards your continuous service. The 2-year clock starts on your first day of work, regardless of any probationary period stated in your contract. There is no separate legal status for "probation" — you are an employee from day one (assuming employee status).

What if I was on a fixed-term contract that was renewed?

If your fixed-term contract was renewed (or extended) without a break of more than one week, your service is continuous across all contracts. If there was a longer gap, continuity may be broken. The reason for the gap is relevant — if it was a "temporary cessation of work" (for example, a school term-time worker), continuity may be preserved.

Can agency workers claim unfair dismissal?

Generally, agency workers are not employees of the end-user (the hirer) and therefore cannot claim unfair dismissal against them. They may be employees of the agency, depending on the contract. The employment status of agency workers is a complex area. If you work through an agency, you should check your contract and seek advice on your employment status.

What about part-time workers?

Part-time workers have exactly the same unfair dismissal rights as full-time workers, including the 2-year qualifying period. The key is establishing that you are an employee with continuous service, not a casual worker or genuinely self-employed contractor.
