Employee Dismissal: a Practical Guide for UK Employers
The need to consider employee dismissal is something most managers and business owners will encounter at some point. Whether you are dealing with a long-standing team member or someone new to the business, getting it right matters. You need to protect your organisation and act fairly, not because it is a box-ticking exercise, but because failure to handle dismissals properly can lead to claims and lengthy disputes down the line.
In my experience as an employment lawyer working with employers across the UK, the facts are straightforward but the application is often tricky. Tribunals will look closely at the reason for the dismissal, the process followed and whether you acted consistently and reasonably. A misunderstanding at any stage can turn what seemed like a straightforward decision into a formal grievance, a tribunal claim or both.
Understanding employee dismissal and when it applies
An employee dismissal happens when you bring an employee’s contract to an end. This might be because of poor performance, misconduct, redundancy or sometimes for what the law calls “some other substantial reason”. It is similar to the definition on GOV.UK but with the added layer that employers must justify the decision and the process they used.
It is important to remember that employees have statutory rights even if they have worked for you only a short time. At the moment, most employees need two years’ service before claiming ordinary unfair dismissal, but that qualifying period is changing over the next year. It may be reduced to six months in 2027, so the standard protections against unfair dismissal are likely to apply sooner than you expect.
Common reasons for employee dismissal
You must be clear about why you are dismissing someone and be able to show that the reason is valid. While every business is different, the law recognises only a few broad categories of fair reasons for dismissal:
- Conduct such as persistent poor behaviour.
- Capability or performance that does not meet reasonable standards.
- Redundancy when the role genuinely ceases to exist.
- Statutory ban, where continued employment breaks the law.
- Some other substantial reason related to the business.
It might seem obvious that gross misconduct, like theft or serious breaches of health and safety policies, can justify dismissal. However, even in those situations, the process you follow matters. You should investigate properly, give the employee a chance to respond and record your steps to show fairness.

Process matters as much as reason in employee dismissal
Tribunals look not just at why you dismissed someone but at how you reached your decision. Even with a seemingly strong reason, a flawed process can turn a lawful decision into an unfair dismissal claim.
Here are key parts of any good process:
- Investigate thoroughly and impartially.
- Share concerns with the employee in writing.
- Hold a meeting where the employee can respond.
- Allow them to be accompanied if they wish.
- Provide the outcome in writing with clear reasons and notice details.
A common mistake is assuming a short service period allows you to cut corners. Even during a probationary period, employees have rights against discrimination and breach of contract. Tribunal decisions often hinge on whether the process was fair and whether you gave the employee reasonable opportunity to address concerns.
If dismissal arises from performance or disciplinary issues, following a clear procedure helps demonstrate reasonableness. You can see more about these steps on our dismissing an employee page.
Examples where employee dismissal often goes wrong
Many employers tell me they acted in good faith but still faced claims. A few scenarios I see regularly include:
A line manager dismisses an employee for alleged misconduct without allowing them to see the evidence or respond to the allegations. The employee then brings an unfair dismissal claim because the decision felt like a surprise rather than a reasoned conclusion.
Another example involves performance issues. An employer terminates someone’s employment with minimal feedback and no performance review records. In a subsequent tribunal case, the employer struggled to show they gave any realistic opportunity to improve.
Both of these could have been reduced risk cases with better preparation and documentation. A clear, consistent approach not only protects your business but also supports trust internally because the process feels fair.
Avoiding tribunal risk and what to do if it happens
Even when you do everything right, some dismissals trigger disputes. Early conciliation through ACAS is a mandatory first step if a claim is lodged. This often provides a chance to settle matters without a full tribunal hearing. It is worth engaging constructively because it demonstrates reasonableness and may save significant costs and time.
One area that deserves particular care involves claims linked to protected characteristics such as age, disability or pregnancy. These claims are automatically unfair and do not require the usual qualifying period. Employers need to remain alert to how decisions may appear when viewed externally, especially where sensitive circumstances exist.
Conclusion
An employee dismissal is one of the most sensitive and technical decisions you will make as an employer. You need a solid reason, a fair process and clear records. Taking short cuts or reacting emotionally can expose you to legal claims and damage confidence within the workplace.
If you would like to strengthen your dismissal procedures and reduce risk, professional support can make a genuine difference. Getting advice early often prevents small issues from becoming expensive disputes.
