Losing your job can feel unfair, but employment law uses a specific legal test. Unfair dismissal can arise when an employer lacks a fair reason or follows an unreasonable process. Employees should also check strict tribunal deadlines before deciding what action to take.
This guide focuses mainly on England, Scotland and Wales, where the Employment Rights Act 1996 applies. Northern Ireland has separate employment legislation and different qualifying rules. Anyone facing an urgent employment dispute should check the rules applying where they work.
An employee may have a claim when an employer lacks a fair reason, follows an unfair process, or terminates employment for a prohibited reason. Most ordinary claims currently require two years’ service. Strict tribunal deadlines apply, and important changes take effect on 1 October 2026 and 1 January 2027.
| Key point | Current position in Great Britain |
|---|---|
| Ordinary qualifying period | Usually two years until 31 December 2026 |
| New qualifying period | Six months from 1 January 2027 |
| Automatically unfair reasons | Many do not require two years’ service |
| Current tribunal deadline | Usually three months minus one day |
| Change from 1 October 2026 | Most tribunal limits become six months minus one day |
| First step before most tribunal claims | Notify Acas for Early Conciliation |
| Current compensatory award cap | Lower of £123,543 or 52 weeks’ gross pay in most ordinary cases |
| Maximum week’s pay for basic award | £751 from 6 April 2026 |
| Major 2027 compensation change | Ordinary compensatory award cap removed from 1 January 2027 |
Key takeaways
* A job loss is not legally unfair merely because the decision feels harsh. * Employers usually need a potentially fair reason and a reasonable procedure. * Current ordinary protection generally starts after two years’ continuous employment. * Some protected reasons can create rights without the normal service requirement. * Tribunal deadlines are short and should be checked immediately. * Major legal changes take effect on 1 October 2026 and 1 January 2027. * Discrimination, contractual and whistleblowing claims can involve separate legal tests.
What counts as unfair dismissal?
The Employment Rights Act 1996 requires employers to show the principal reason for ending employment. The reason must fall within a recognised category or amount to another substantial reason. A tribunal then considers whether the employer acted reasonably in the circumstances.
A case can therefore turn on both why the employer acted and how it acted. An employer might have a legitimate concern but still use an unreasonable procedure. Equally, following a detailed process will not rescue a decision based on a prohibited reason.
The legal question depends heavily on the evidence available. Letters, emails, meeting notes, policies and performance records can all become important. Employees should preserve relevant documents as soon as a dispute develops.
What are the five potentially fair reasons?
The law recognises five broad grounds that can potentially justify ending someone’s employment. A recognised reason does not make the decision automatically lawful. The employer must still act reasonably and use a suitable process.
| Potentially fair reason | Typical example |
|---|---|
| Capability or qualifications | Persistent poor performance after suitable support |
| Conduct | Misconduct or serious disciplinary problems |
| Redundancy | A genuine reduction or disappearance of the employee’s role |
| Statutory restriction | Continuing employment would breach a legal requirement |
| Some other substantial reason | A serious business reason outside the other categories |
Capability cases often require warnings, support and a realistic chance to improve. Conduct cases commonly require a proper investigation before a final decision. Redundancy cases involve their own consultation and selection requirements.
Legalyst’s guide to Civil Service redundancy explains several redundancy issues in more detail. Redundancy is a form of termination, not a separate concept in employment law. Selection can still be challenged where the process or underlying reason is unlawful.
When is the reason automatically unfair?
Certain reasons receive stronger statutory protection. These include many cases involving pregnancy, family leave, whistleblowing, trade union activity and health and safety rights. Asking for certain statutory workplace rights can also receive protection.
In many automatically protected cases, the usual two-year service requirement does not apply. This distinction matters especially for employees with short service. A person dismissed after several months might therefore still have a viable statutory claim.
Health and safety disputes can overlap with other workplace issues. Legalyst’s head injury at work guide explains how employment concerns can arise separately from injury compensation. Employees should avoid assuming one legal deadline applies to every potential claim.
Why does the employer’s procedure matter?
A fair reason is only part of the legal assessment. Employers should normally investigate concerns, explain the allegations and give employees an opportunity to respond. Where appropriate, a suitable appeal should also be available.
The Acas Code is particularly important in misconduct and capability cases. A failure to follow a fair process can strengthen an employee’s position. Tribunals still consider the facts and resources available to the particular employer.
Employees should read the staff handbook and any disciplinary or capability policy. Where possible, they should request important decisions in writing. Written evidence can later clarify what happened and why.
Who can bring a claim?
For a standard claim in Great Britain today, the claimant normally needs to have been an employee. They also generally need at least two years of continuous service. That rule remains relevant for terminations taking effect before 1 January 2027.
Significant exceptions exist to that service requirement. Automatically protected reasons are an important example. Discrimination rights also operate separately and do not generally require two years’ employment.
Employment status can itself become disputed. Someone described as self-employed might argue that the practical working relationship made them an employee. Status questions can be fact-sensitive and may require individual advice.
What should you do after losing your job?
Act quickly because several practical steps can protect your position. Start by obtaining the termination letter and checking the reason given. Keep copies of relevant contracts, policies, warnings, emails, messages and meeting notes.
Next, check whether your employer offers an internal appeal. An appeal can give the employer an opportunity to reconsider the decision. It does not automatically stop the deadline for starting the tribunal process.
Then check the applicable limitation date and consider Acas Early Conciliation. Notification to Acas is required before most employment tribunal claims in Great Britain. The limitation clock is affected while the Early Conciliation process operates.
A practical sequence is:
1. Confirm the effective date your employment ended. 2. Ask for the reason in writing where appropriate. 3. Collect your contract, policies and correspondence. 4. Write a timeline while events remain fresh. 5. Submit any internal appeal promptly. 6. Calculate the tribunal deadline immediately. 7. Notify Acas within the relevant time limit. 8. Consider legal advice if the facts or claims are disputed.
How long do you have to make a tribunal claim?
As of 30 September 2026, the usual limit for an ordinary unfair-dismissal tribunal claim is three months minus one day from the effective end date. Starting an internal appeal does not mean you can ignore that limit. ACAS Early Conciliation can pause the limitation calculation.
A major change begins on 1 October 2026. For most employment tribunal claims, the time limit will become six months minus one day. Employees should still calculate their deadline using the rules that apply to their case, rather than assuming six months is available.
Some applications have much shorter deadlines. For example, qualifying interim-relief applications can require action within seven days. Whistleblowing and certain representative cases can therefore require urgent specialist attention.
How much compensation could you receive?
Compensation usually includes a basic award and, where appropriate, a compensatory award. The compensatory element focuses principally on financial loss caused by the termination. Factors such as lost earnings and future loss can therefore matter.
For relevant events from 6 April 2026, the statutory week’s-pay ceiling used for the basic award is £751. The ordinary compensatory award is currently capped at the lower of £123,543 or 52 weeks’ gross pay. Certain protected categories are excluded from the ordinary compensatory ceiling.
An award is not guaranteed simply because an employee succeeds on liability. Tribunals can examine actual losses, mitigation and the circumstances surrounding the case. Reinstatement or re-engagement can also be available in appropriate cases.
What changes on 1 January 2027?
The Employment Rights Act 2025 makes major changes for workers in England, Scotland and Wales. From 1 January 2027, ordinary protection will generally begin after six months instead of two years. The existing statutory cap on the ordinary compensatory award will also be removed.
These changes do not mean employers lose the ability to manage poor performance or misconduct. Employers can still terminate employment for legitimate reasons when the decision and procedure are fair. The practical significance is that many employees will gain ordinary statutory protection much earlier.
Northern Ireland is different because employment law is devolved there. Its normal qualifying period is currently one year rather than two years. The January 2027 Great Britain reforms should not be assumed to apply there.
What about discrimination, wrongful and constructive claims?
A workplace termination can create more than one possible legal issue. Discrimination may arise where treatment is connected with protected characteristics under equality law. Employees do not need two years’ service before bringing a discrimination claim.
Legalyst’s workplace discrimination guide covers evidence, workplace complaints and tribunal issues. Discrimination compensation is assessed under different rules from an ordinary employment termination claim. The legal tests should therefore be considered separately.
Wrongful termination concerns breach of contract, often involving notice or notice pay. Constructive termination arises when an employee resigns in response to a sufficiently serious breach by the employer. These concepts should not be treated as interchangeable with the statutory fairness test.
Evidence that can strengthen your position
Contemporaneous evidence often matters more than later recollections. Keep the employment contract, staff handbook and relevant workplace policies. Preserve emails and messages concerning the reason for the decision.
Meeting invitations, investigation notes, warnings and appeal correspondence can also be important. Performance reviews may show whether earlier concerns existed before termination. Pay records can help calculate financial loss.
Employees should keep evidence lawfully and respect confidentiality duties. Taking confidential business material without authority can create separate problems. A solicitor or adviser can help identify relevant and appropriate evidence.
Frequently asked questions
Can I claim unfair dismissal with less than two years’ service?
Possibly, depending on the reason for the termination and other legal rights involved. Automatically protected reasons may not require the normal qualifying period. From 1 January 2027, ordinary protection in Great Britain will generally start after six months.
Is redundancy always a fair reason to lose your job?
No, although genuine redundancy is a potentially fair statutory reason. The employer must still use a reasonable process and fair selection approach. A sham redundancy or discriminatory selection can create legal problems.
Can I take my employer to a tribunal without appealing internally?
A tribunal claim can sometimes proceed even without an internal appeal. Still, failing to use a reasonable appeal process can affect how the dispute develops. You must not let an internal procedure cause you to miss the statutory deadline.
Do I have to contact Acas first?
For most employment tribunal claims in Great Britain, you must notify Acas before presenting the claim. Acas normally offers Early Conciliation to explore whether the dispute can be settled. The procedure also affects how the final tribunal deadline is calculated.
Can I get my job back?
A tribunal can order reinstatement or re-engagement in suitable cases. Financial compensation is another possible remedy. The appropriate outcome depends on the circumstances and what the tribunal orders.
What to do next
Check your termination date first because employment deadlines can expire quickly. Gather your written evidence and review any available appeal procedure. Then check the applicable Acas and tribunal requirements before the limitation period ends.
Related Legalyst resources cover redundancy, discrimination and workplace injury issues in more detail. Readers considering professional representation can also review Legalyst’s no-win-no-fee solicitor guide. These resources provide general information, not advice on an individual case.
Employment disputes can depend on facts that are not obvious from a termination letter alone. Early advice may be especially important where whistleblowing, discrimination, pregnancy, health and safety, or a seven-day interim-relief deadline could apply. For official guidance, Acas and GOV.UK guidance on dismissal should remain key reference points.
