Understanding Dismissal: Exploring Wrongful and Unfair Termination in UK Employment Law

If you’re running a business and managing employees, you’ll probably face tough personnel decisions at some point. Knowing how to handle dismissals properly-and how UK law defines and protects against wrongful or unfair termination-can protect your company against costly mistakes. But what exactly is a dismissal in a legal sense? And how can you make sure you’re handling things the right way?

Dismissing staff is rarely anyone’s favourite task. Still, understanding the difference between lawful, wrongful, and unfair dismissal is essential for all employers. In this guide, we’ll break down everything you need to know about dismissals under UK employment law, what the right processes look like, and how to stay on the right side of the rules. Let’s get started.

What Is a Dismissal in UK Employment Law?

In simple terms, a dismissal is when an employer ends an employee’s contract of employment. It’s a formal termination instigated by the employer, not a resignation or other form of employment ending.

There are a few core ways dismissal can occur:

• The employer gives notice, ending the employee’s contract on a set date.
• The employer “summarily” dismisses the employee (instant dismissal, usually for gross misconduct).
• A fixed-term contract comes to its end and isn’t renewed.
• Redundancy: when the employee’s role is no longer needed.

The law sets strict guidelines around when a dismissal is considered fair, unfair, or wrongful. Failing to follow correct procedure-whether for economic reasons, misconduct, or underperformance-can put your business at risk of expensive claims.

Why Does This Matter for Employers?

Dismissing an employee without a valid legal reason-or not following proper steps-can result in claims for unfair dismissal or wrongful dismissal at an employment tribunal. Each has its own legal definition and risks.

Understanding your rights and obligations isn’t just about compliance; it’s an essential part of responsible management, reputation preservation, and employee relations.

How Does the Law Define “Struck Out” in Employment Tribunals?

If you’ve heard the term “struck out” in the context of employment law, it simply means a tribunal claim has been dismissed-usually because it has no reasonable prospect of success, or because the claimant hasn’t complied with procedural steps. If an employee brings a claim for unfair or wrongful dismissal and it’s struck out, the case is closed without a full hearing.

For business owners, understanding how dismissal cases are handled in tribunals is important for managing legal risk. If you follow best practice and fair procedures for dismissals, you’ll be in a stronger position if a claim does arise.

What Is the Difference Between Wrongful Dismissal and Unfair Dismissal?

The terms wrongful dismissal and unfair dismissal are often confused, but they’re quite different-both in legal definition and in what an employee must prove.

Wrongful Dismissal Explained

Wrongful dismissal is essentially a breach of contract claim. It happens if you, as an employer, terminate an employee’s contract without giving the full notice period required, or without following the terms of the employment contract.

• Example: If an employee is entitled to one month’s notice but you dismiss them with only a week’s notice (and it isn’t gross misconduct), this could be wrongful dismissal.

The law here is about contract rights-the employee is owed what’s promised in the contract. Usually, the claim is for the “notice pay” the employee should have received.

Unfair Dismissal Explained

Unfair dismissal is a statutory claim based on employment law, not just the contract. The Employment Rights Act 1996 gives most employees with at least two years’ continuous service the right not to be unfairly dismissed.

Here’s how unfair dismissal claims differ from wrongful dismissal:

• The focus is on whether you had a “fair reason” to dismiss (like misconduct, redundancy, or job capability), and whether you followed a fair process.
• Even if you paid correct notice, the dismissal could be judged “unfair” if you didn’t have valid reasons or didn’t consult/ warn properly.

Common examples of unfair dismissal include sacking someone for whistleblowing, discrimination, or for asserting a statutory right. In these cases, the employment tribunal can award compensation or order re-employment.

When Is a Dismissal Fair (or Unfair)?

For a dismissal to be “fair” under UK law, you need two things:

1. A fair reason for dismissal
2. A fair process in how you carry it out

The Five Legally Recognised “Fair” Reasons

There are only five main reasons accepted by tribunals as fair for ending an employee’s contract:

• Conduct: The employee did something seriously wrong (e.g., gross misconduct)
• Capability: The employee isn’t able to perform the job, due to lack of skill, illness, or qualifications
• Redundancy: The role is no longer needed
• Statutory Bar: It’s illegal to keep the employee in the role (for example, they lose the right to work in the UK)
• Some Other Substantial Reason: Another significant business reason (e.g., reorganisation)

You can find more about lawful employee termination and best practice in our employer’s guide to dismissal article.

What Does a “Fair Process” Involve?

Having a fair reason isn’t enough. As an employer, you must also:

• Investigate the circumstances before making a decision
• Warn the employee about the risk of dismissal (unless it’s gross misconduct)
• Offer the employee a chance to respond or improve (like through a performance review or warning process)
• Hold a formal meeting (and let the employee bring a companion)
• Allow for an appeal

If you skip these steps or don’t keep records, a tribunal may decide even a genuine reason was carried out unfairly. It’s always smart to document every step and follow your company’s disciplinary or capability procedure. For more information on managing fair disciplinary processes, read our guide here.

When Can an Employee Claim Unfair Dismissal?

Not every employee can claim unfair dismissal. Legally, an individual usually needs at least two years’ continuous service. There are exceptions-if the dismissal is for an “automatically unfair” reason (like pregnancy, whistleblowing, or asserting statutory rights), the two-year rule does not apply.

Bear in mind that employees on fixed-term contracts, those made redundant, or those accused of gross misconduct, may still have grounds for a claim. It’s important to seek professional advice before dismissing anyone-especially where the situation is complex.

What Steps Should Employers Take Before Dismissing Someone?

No one wants a tribunal on their hands. Taking the right steps before dismissal is key:

1. Review the reason: Are you relying on one of the five fair reasons?
2. Follow process: Did you warn the employee, investigate properly, and give them a chance to improve?
3. Consult your policies: Are disciplinary, redundancy, or absence procedures being followed?
4. Keep clear records: Minutes, warnings, written evidence, and notes matter.
5. Get legal advice: If you’re unsure, protect yourself and your business!

Following a clear and consistent process will put you in a strong position, should any claim be raised later. For more detailed steps, see our advice on how to dismiss an employee properly.

What’s at Stake If You Get Dismissals Wrong?

Unfair or wrongful dismissal claims can be expensive and time-consuming. Compensation may include:

• “Notice pay” owed for wrongful dismissal
• Compensation for lost earnings due to unfair dismissal
• Possible reinstatement

You’ll also face costs, lost productivity, and a damaged reputation. Prevention through solid processes and documentation is always better than managing a dispute after the fact.

How Can You Avoid Wrongful and Unfair Dismissal Risks?

Here’s what every small business owner should do:

• Have clear, written employment contracts for every employee.
• Implement, follow, and update staff handbooks and disciplinary processes.
• Apply processes consistently and record every step.
• Regularly review whether your staff contracts, policies and procedures are up to date with the latest law.
• Seek legal advice before making a final decision on dismissal, especially with complex employee issues.

It’s also wise to review our gross misconduct checklist so you’re prepared if issues arise. Not every situation is straightforward, and having the correct contracts and company policies in place can help you stay compliant-and confident.
