Unfair Dismissal UK: Complete Guide to Your Rights and Claims

What is Unfair Dismissal?

Unfair dismissal is a statutory right protecting employees from arbitrary job loss, requiring employers to prove a fair reason and reasonable action.

In UK employment law, unfair dismissal protects employees who have at least two years' continuous service from being sacked without valid grounds or proper process. The Employment Rights Act 1996 sets out that a dismissal is fair only if the employer has one of five potentially fair reasons and acts reasonably in treating that reason as sufficient for dismissal.

Tribunals examine both the reason given and the procedure followed, such as investigations and hearings. For example, if dismissed for poor performance without prior warnings or support, it could be ruled unfair.

This protection does not apply to self-employed individuals or workers, only employees meeting the qualifying criteria.

The Qualifying Period for Unfair Dismissal Claims

Most unfair dismissal claims require two years of continuous employment, but exceptions exist for automatically unfair reasons.

Under section 108 of the Employment Rights Act 1996, you generally need two years' continuous service with the same employer to claim ordinary unfair dismissal. This period starts from your first day of employment and includes time on maternity leave or sick leave.

Continuity breaks only in specific cases like dismissal then rehire. Short gaps under a week do not interrupt service.

However, no qualifying period applies for automatically unfair dismissals, such as whistleblowing or discrimination.

Fair Reasons for Dismissal Under UK Law

Employers must show one of five potentially fair reasons: conduct, capability, redundancy, legal restrictions, or some other substantial reason.

Section 98 of the Employment Rights Act 1996 lists five potentially fair reasons for dismissal. For conduct, employers must investigate misconduct thoroughly before acting.

Capability covers poor performance or illness; redundancy when the role disappears. 'Some other substantial reason' (SOSR) is a catch-all for business needs like refusing changes.

Even with a fair reason, the employer must follow a fair procedure, guided by the ACAS Code of Practice on disciplinary and grievance procedures.

• Misconduct (e.g. theft, fighting)
• Capability or qualifications
• Redundancy
• Cannot continue without breaking law
• Some other substantial reason (SOSR)

Automatically Unfair Reasons for Dismissal

Some reasons make dismissal automatically unfair, like whistleblowing or union activities, with no qualifying period needed.

Certain reasons render dismissal unfair regardless of procedure or service length, per sections 99, 100, 103 etc. of the Employment Rights Act 1996. These include pregnancy, health and safety concerns, protected disclosures (whistleblowing), and asserting statutory rights.

If the principal reason is one of these, tribunals presume unfairness, shifting burden to the employer to disprove.

Examples: sacked shortly after maternity leave announcement or raising safety issues.

• Protected disclosure (whistleblowing)
• Trade union membership/activities
• Pregnancy or maternity
• Health and safety activities
• Family emergencies

Time Limits and ACAS Early Conciliation

You have three months less one day from dismissal to start ACAS early conciliation, which pauses the deadline.

Early conciliation via ACAS is mandatory before tribunal claims, extending your time limit. The standard three-month minus one day from effective termination date applies, per section 111 Employment Rights Act 1996.

During conciliation, time stops; if unsuccessful, you get a certificate extending to at least one month after.

Late claims need 'just and equitable' exception, rarely granted without good reason like illness.

1. Contact ACAS within 3 months minus 1 day
2. Complete early conciliation
3. Get certificate and submit to tribunal within one month

How to Make an Unfair Dismissal Claim

Start with ACAS, then submit form ET1 to the employment tribunal with evidence of unfairness.

After early conciliation certificate, file online ET1 form detailing dismissal facts, reason given, and why unfair. No fee since 2017.

Gather evidence: emails, warnings, witness statements. Tribunals assess reasonableness objectively.

Hearing involves both sides presenting cases; self-representation is common with preparation.

1. Obtain ACAS certificate
2. Complete ET1 form
3. Exchange documents/bundles
4. Attend preliminary and final hearings

Remedies and Compensation Available

Successful claims can lead to reinstatement, re-engagement, or compensation including basic and compensatory awards.

Remedies under Employment Rights Act 1996 include reinstatement (job back), re-engagement, or money. Basic award mirrors redundancy: age, service, week's pay (capped).

Compensatory award covers losses like earnings (capped around £115,000 currently), up to two years' loss. Polkey reduction if you contributed to unfairness.

Interim relief possible for automatically unfair cases like whistleblowing.

Common Mistakes to Avoid in Unfair Dismissal Claims

Avoid delays, poor evidence, ignoring ACAS, or resigning prematurely without constructive dismissal grounds.

Many lose claims by missing deadlines or inadequate evidence. Resigning without establishing constructive dismissal forfeits ordinary claim rights.

Failing to follow internal appeals weakens cases. Overlooking automatically unfair aspects limits options.

Self-representers succeed by using free resources like Citizens Advice.

• Delaying ACAS contact
• Weak bundles/missing deadlines
• Not appealing internally
• Claiming without qualifying service
