What Counts as Unfair Dismissal and How to Recognise It

Unfair dismissal is a key concept in employment law in England and Wales. It refers to situations where an employer terminates an employee's contract in a way that the law regards as unjust. Understanding what counts as unfair dismissal helps employees know whether they have legal grounds to challenge the decision and guides employers on how to avoid legal risk. This article explains the law clearly, covers legal processes and time limits, and provides practical context for employees, students and solicitors alike.

What Is a Dismissal?

A dismissal occurs when an employer ends a person's employment. This can include:

• Termination by the employer with or without notice.
• Failure to renew a fixed-term contract at its end.
• Situations where the employee resigns because of a serious breach of contract by the employer (known as constructive dismissal).

Unfair dismissal is not limited to outright firing; substantial changes to pay, duties or contract terms imposed without agreement may in some cases amount to an effective dismissal.

When Does Unfair Dismissal Apply?

To bring a claim for ordinary unfair dismissal at an employment tribunal, an employee generally must:

• Be an employee (not just a worker, e.g. certain contractors).
• Have worked for the employer for the qualifying period (currently two years' continuous service for most ordinary claims).

However, many situations are treated as automatically unfair and do not require the qualifying period (for example pregnancy or whistleblowing).

Note: UK employment law is evolving. A new Employment Rights Act is progressing through Parliament and includes proposals to reduce the qualifying period for unfair dismissal rights to six months' service from the current two years for employees who begin employment after a specified date.

Statutory Fair Reasons for Dismissal

Under the Employment Rights Act 1996, employers must show a fair reason for dismissal. There are five statutory categories that might justify a dismissal:

1. Capability or qualifications – ability to do the job or necessary certifications.
2. Conduct – behaviour issues or misconduct.
3. Redundancy – genuine redundancy due to business needs.
4. Statutory restriction – legal prohibition on continuing to employ someone (e.g. loss of required licence).
5. Some other substantial reason (SOSR) – a catch‑all category for other legitimate business reasons.

If an employer cannot show that one of these reasons applies, a tribunal may find the dismissal unfair.

Procedural Fairness

Even where a potentially fair reason exists, a dismissal can still be unfair if the employer does not follow a reasonable procedure. This includes:

• Investigating the issue before dismissing.
• Giving the employee information and an opportunity to respond.
• Following internal disciplinary and grievance procedures.
• Considering alternatives to dismissal.

Tribunals often refer to the Acas Code of Practice on Disciplinary and Grievance Procedures to assess whether the employer acted reasonably. Failure to follow the Code can lead to increased compensation.

Automatically Unfair Dismissal

Some dismissals are automatically unfair, regardless of service length and procedure. These include dismissal because an employee:

• Is pregnant, on maternity leave or related to family rights such as paternity or adoption.
• Took or sought family‑related statutory leave.
• Is a trade union member or representative.
• Took part in protected industrial action.
• Made a whistleblowing disclosure (reporting wrongdoing).
• Asserted other statutory employment rights (e.g. flexible working requests or minimum wage).

Automatically unfair dismissal protections apply immediately, meaning an employee may bring a claim even without long service.

Constructive Unfair Dismissal

Constructive dismissal occurs where the employer's conduct fundamentally breaches the contract, leaving the employee no option but to resign. Examples include lowering pay without consent or creating a hostile workplace. Constructive dismissal is treated as an unfair dismissal if the reason and circumstances meet the legal test.

Discrimination and Unfair Dismissal

Dismissal may also be unlawful if it is discriminatory under the Equality Act 2010 because of protected characteristics such as sex, race, disability or age, irrespective of whether there was a fair reason. If discrimination is alleged alongside unfair dismissal, separate compensation may be awarded.

How to Challenge Unfair Dismissal

Early Conciliation

Before submitting a tribunal claim, the claimant must notify Acas and go through Early Conciliation. This is a free service where Acas attempts to help both sides reach a settlement.

Employment Tribunal Claim

If conciliation does not resolve the dispute, the claimant can submit a claim to the employment tribunal. The tribunal assesses whether the dismissal was unfair based on reason and fairness of procedure.

Time Limits

Time limits are strict:

• The basic time limit for unfair dismissal claims is three months minus one day from the effective date of termination (usually the last day of employment or last day of notice).

Early conciliation stops the clock while it runs, but the initial notification to Acas must still fall within the time limit.

Remedies and Compensation

If a tribunal finds a dismissal unfair, remedies can include:

• Reinstatement (employee returns to the same job).
• Re‑engagement (employee returns under different terms).
• Compensation, which generally includes a basic award and a compensatory award for loss of earnings. Awards may be increased if the Acas Code was not followed.

Compensation is subject to statutory caps, which the incoming Employment Rights Bill proposes to remove in certain cases, potentially allowing uncapped compensation for unfair dismissal.

Practical Examples

• No fair reason given: An employee is dismissed with vague or no explanation. Without a recognised fair reason, the dismissal may be unfair.
• Failure to follow procedure: An employer dismisses without investigation or hearings, even if misconduct is alleged.
• Automatically unfair reason: An employee is dismissed after requesting flexible working. No service length is required.
• Constructive dismissal: Persistent insults and unlawful changes to contract cause resignation; the employee claims dismissal was effectively forced.

Key Takeaways

Unfair dismissal occurs when an employer ends employment without a fair reason, acts unreasonably in using a potentially fair reason, or dismisses for automatically unfair reasons. Claims usually require qualifying service and must follow Acas early conciliation within the strict time limits. Remedies can include compensation and reinstatement. Understanding your rights and the legal process helps in recognising whether a dismissal is unfair and what steps to consider next.
