What Is Wrongful Dismissal and How Does It Differ from Unfair Dismissal?

In UK employment law, dismissal claims generally fall into two main categories: wrongful dismissal and unfair dismissal. Although they often arise from the same termination of employment, they are legally distinct. Each is based on different rights, different legal tests, and different routes of enforcement.

Understanding the difference is important because it affects eligibility, evidence requirements, time limits, and potential compensation. Claims are usually brought in the Employment Tribunal Employment Tribunal, often after early conciliation through ACAS Advisory, Conciliation and Arbitration Service.

What Is Wrongful Dismissal?

Wrongful dismissal is a breach of contract claim. It occurs when an employer ends employment in a way that violates the terms of the employment contract.

It is not concerned with whether the dismissal was “fair” in a broader sense. Instead, it focuses strictly on contractual obligations.

Common examples of wrongful dismissal

Wrongful dismissal may occur where an employer:

• Dismisses an employee without giving the correct contractual or statutory notice
• Fails to pay notice pay (payment in lieu of notice) where required
• Ends a fixed-term contract early without contractual authority
• Dismisses immediately without justification for gross misconduct
• Breaches a contractual disciplinary or dismissal procedure

The legal basis is contractual rather than statutory, meaning it arises from common law principles rather than a fairness test set out in legislation.

Key point

Wrongful dismissal is about whether the employer breached the employment contract, not whether the dismissal was reasonable or justified overall.

What Is Unfair Dismissal?

Unfair dismissal is a statutory claim under the Employment Rights Act 1996. It examines whether the employer acted reasonably in dismissing the employee.

A dismissal may be unfair if:

• The employer did not have a valid reason (such as conduct, capability, redundancy, or legal restriction)
• The employer did not follow a fair procedure
• The decision to dismiss was not reasonable in the circumstances

Guidance from ACAS confirms that employers are expected to follow a fair disciplinary or dismissal process, usually aligned with the ACAS Code of Practice Advisory, Conciliation and Arbitration Service.

Qualifying requirements

In most cases, employees must have at least two years' continuous service to bring an unfair dismissal claim, except in cases of automatic unfair dismissal (for example, whistleblowing or discrimination-related dismissal).

Tribunal assessment

The Employment Tribunal Employment Tribunal assesses:

• The employer's reason for dismissal
• Whether that reason was genuine
• Whether a fair process was followed
• Whether dismissal was within the range of reasonable responses

Key Differences Between Wrongful and Unfair Dismissal

Although both claims relate to termination of employment, they differ significantly.

1. Legal basis

• Wrongful dismissal: Contract law
• Unfair dismissal: Employment law (statute)

2. Focus of the claim

• Wrongful dismissal: Whether contract terms were breached
• Unfair dismissal: Whether the dismissal was fair and reasonable

3. Notice and procedure

• Wrongful dismissal: Focuses heavily on notice pay and contractual procedure
• Unfair dismissal: Focuses on fairness of reason and process

4. Length of service requirement

• Wrongful dismissal: No minimum service required
• Unfair dismissal: Usually requires two years' service (with exceptions)

5. Compensation

• Wrongful dismissal: Typically limited to financial loss arising from breach of contract (often notice pay)
• Unfair dismissal: Can include basic award, compensatory award, and other statutory elements depending on loss and circumstances

6. What must be proven

• Wrongful dismissal: Breach of contract terms
• Unfair dismissal: Lack of fair reason and/or unfair procedure

Constructive Dismissal and Related Concepts

Constructive dismissal overlaps with both concepts but is legally distinct.

It occurs where an employee resigns because of a serious breach of contract by the employer, such as:

• Non-payment of wages
• Significant unilateral changes to working conditions
• Bullying or serious workplace misconduct

This may give rise to both:

• A wrongful dismissal claim (breach of contract), and/or
• An unfair dismissal claim (if qualifying conditions are met)

Time Limits for Claims

Time limits are strict:

• Unfair dismissal: Usually 3 months minus one day from the date employment ended
• Wrongful dismissal: Generally 6 years in England and Wales (as a contractual claim), but usually brought quickly alongside tribunal proceedings

Before submitting a claim, employees are usually required to contact ACAS Advisory, Conciliation and Arbitration Service for Early Conciliation, which is mandatory in most cases.

Choosing the Correct Claim

In practice, claimants often bring both claims together:

• Wrongful dismissal addresses financial loss from breach of contract (often notice pay)
• Unfair dismissal addresses the fairness of the employer's decision-making process

This dual approach is common because the legal tests do not overlap entirely.

Practical Steps After Dismissal

Where dismissal is disputed, typical steps include:

1. Reviewing the employment contract for notice and disciplinary terms
2. Checking whether proper notice or payment was given
3. Raising an internal appeal if available
4. Contacting ACAS for Early Conciliation
5. Considering an Employment Tribunal claim if unresolved
6. Gathering evidence (emails, contracts, policies, meeting notes)

Common Misunderstandings

“Unfair” does not automatically mean “wrongful”

A dismissal can be:

• Unfair but not wrongful (fair notice given, but poor procedure), or
• Wrongful but not unfair (notice not paid, but fair reason existed)

Summary dismissal

Immediate dismissal without notice is only lawful where there is gross misconduct and the contract permits summary termination.

Key Takeaways

Wrongful dismissal and unfair dismissal are separate legal concepts. Wrongful dismissal is based on breach of contract, usually involving notice or pay issues. Unfair dismissal is based on statutory protection against unreasonable or procedurally unfair termination. Claims are assessed differently by the Employment Tribunal Employment Tribunal and often require involvement with ACAS Advisory, Conciliation and Arbitration Service before formal proceedings.

Understanding the distinction is essential for identifying the correct legal route, relevant time limits, and potential remedies.
