How to Dismiss an Employee for Poor Performance

How to dismiss an employee for poor performance

Understanding how to dismiss an employee for poor performance is something many employers ask me about. It is one of those issues where a clear and fair process protects you from unnecessary risk. I have advised many small business owners who tried to “give someone one last chance” only to find that the process had already drifted away from what a tribunal would expect. That is why it helps to take a steady and practical approach from the very first signs that performance is slipping.

You may already have concerns. Perhaps deadlines are missed or customer service has dipped. Maybe colleagues have raised quiet complaints that something “isn’t quite right”. In UK tribunals, these underlying signs often appear months before anything formal begins. When I speak to employers, they often say they tried to be patient for too long, which then makes the final step feel harder. Even so, following a structured approach makes the whole situation more manageable and more defensible.

Why structure matters when learning how to dismiss an employee for poor performance

Most performance cases start informally. You pull the employee aside, raise the concern and hope that things pick up. Sometimes they do, although in my experience the improvement can be short lived if the root problem has not been understood. I recall an engineering client who assumed an employee “just needed to focus more”. It later became clear that he had never been trained properly on the new system. Once that was sorted, the issue vanished. Taking time to look for possible cause is always worthwhile.

Although informal steps help, you still need to be able to show that you went through a reasonable process. This is where many employers trip up. You may feel the evidence is obvious, yet a tribunal will still expect some record of what was discussed, any support offered and a genuine opportunity for improvement. Transitioning into a formal process too early can feel heavy handed, but waiting too long carries risk. Getting the balance right is important.

At this stage, it can help to review your capability policy. Most employers have one, although they are not always used. You can also check whether the employee has raised discrimination or health issues before. If they have, you may need to think about reasonable adjustments or medical evidence. This is one of those times where tailored legal guidance gives you more confidence to move forward.

Setting clear expectations before any decision

Before you ever reach the point of dismissal, you will almost always need to set out a performance improvement plan. Plans vary in size and length but usually include a short list of measurable expectations. They also include realistic timescales. I have seen employers add twenty separate targets which no employee could follow. I have also seen plans so vague that the employee could not understand what was required. A workable plan sits somewhere in the middle.

Examples might include: respond to customer enquiries within a set time, maintain accurate records or complete weekly stock checks. These are simple but measurable. Regular review meetings should follow and you should take notes. Even where the employee disagrees, the record itself shows that you behaved reasonably. That point often carries weight in a tribunal.

Sometimes an employee blames others or offers excuses that seem weak. Try to explore whether there is anything behind what they are saying. There may be an underlying issue such as poor induction, outdated equipment or a misunderstanding about duties. Fixing these early often avoids escalation. Including a single supporting link such as EBS Law can help keep your internal notes consistent with the guidance you follow.

Moving into formal warnings when deciding how to dismiss

Where the plan does not work or progress stalls, you may move into the formal stage. This normally includes a meeting with the employee. Try to give them enough detail to prepare, because springing evidence on them can be seen as unfair. After listening to their explanation, you may issue a written warning. This is often the first formal step in capability procedures.

Warnings should be specific. Avoid general phrases like “improve attitude”. Instead, focus on the tasks that are not being done correctly. The warning should also explain the consequences of further failings. Tribunals tend to look closely at warnings. If a warning is vague or disproportionate, it can undermine the fairness of the dismissal later.

After a warning, you should still offer support. That might include refresher training or shadowing a more experienced colleague. Even though the employee is now in a formal process, they should still have a fair chance to improve. Keeping an open mind is important. Employers sometimes tell me they feel “the decision is obvious”, but the tribunal expects a genuine review of progress.

While this stage continues, it can be helpful to revisit any previous internal processes. If there have been past grievances, earlier disciplinary steps or relevant emails, check these now. A tribunal will often look at the full history.

Reaching the end of the road and deciding how to dismiss an employee for poor performance

You may reach a point where improvement has not happened. At this stage, dismissal can be considered. This is often difficult for small business owners who feel loyal to long standing staff. Even so, if performance remains below the required standard and you have followed a clear process, dismissal can be fair.

Before making the final decision, invite the employee to a further meeting. Give them notice of the purpose, provide the relevant documents and allow them to be accompanied. After hearing their comments, you may decide that dismissal is the only available outcome. If so, confirm this in writing and offer the right of appeal. Appeals matter. They give the employee a final chance to comment and they show that you acted reasonably.

You should also be aware of potential alternative roles. This is rarely a strict requirement in capability cases, although tribunals may expect you to consider it where roles are similar. If you have no alternative, simply record that fact.

Even once the dismissal is complete, make sure any outstanding holiday pay or notice pay is handled correctly. If the employee has worked for you for less than two years, the risk of an ordinary unfair dismissal claim is lower, although discrimination or whistleblowing issues can still cause claims. When in doubt, you can always seek direct advice. Many employers also revisit related policies at this stage, including absence management policies and general HR support frameworks.

Conclusion

As you work through these steps, you may find that the overall process feels longer than expected. Capability cases require patience because you need to show that you gave the employee a fair chance. Even though many employers hope for quick resolutions, taking steady and well recorded steps puts you in a safer position later. If you are ever unsure, tailored employment law advice for employers helps you keep everything on track.

Each case is different. Some employees turn things around once they understand what is expected. Others do not. In every situation, the key is consistency. Follow your process, record the steps you take and always give the employee a real opportunity to improve. When you do that, dismissals are more likely to be upheld by a tribunal.
