How to manage gross misconduct as a small business or charity in 8 steps

Let’s be honest – dealing with gross misconduct isn’t something most small business or charity leaders ever look forward to. But when serious issues crop up, it’s vital to act quickly and fairly.

Handled well, it protects your people, your values and your organisation’s reputation. Handled badly… well, that’s when things can spiral into legal disputes, lost time and a whole lot of stress you really don’t need.

If you suspect an employee of gross misconduct, here’s a step-by-step guide to help you navigate the process with confidence, care and compliance.

What is gross misconduct?

Gross misconduct is the kind of behaviour that seriously damages the trust between an employer and an employee. In many cases, it can justify dismissal without notice – but only if you follow the right process.

Here are some common examples:

• Theft, fraud or dishonesty
• Physical violence or threats
• Harassment, bullying or discrimination (including sexual harassment)
• Serious breaches of confidentiality or data protection
• Gross negligence that puts others at risk or causes serious damage
• Being under the influence of alcohol or drugs at work
• Acting in a way that breaches your organisation’s safeguarding procedures

It’s not just a case of “something bad happened” – it has to be serious enough to undermine the working relationship altogether.

Why process matters (even if the behaviour seems obvious)

It’s tempting to think, “Well, this is clearly gross misconduct – I’ll just sack them and move on”. But even when the misconduct seems clear-cut, skipping the proper process can lead to unfair dismissal claims, legal costs and reputational damage.

If you’re a small business or charity, that’s not just a headache – it can be a real risk to your organisation.

That’s why it’s so important to follow the Acas Code of Practice, which sets out what a fair disciplinary process looks like.

Step-by-step: Managing gross misconduct the right way

1. Consider suspension (if necessary). Only suspend the employee if it’s absolutely needed – for example, to protect others or prevent tampering with evidence. If you do suspend, make it clear that it’s a neutral action, not a punishment.

2. Investigate fairly. Carry out a thorough investigation to understand what happened. This means speaking to relevant people, reviewing evidence and keeping an open mind. You’re gathering facts – not jumping to conclusions.

3. Send a clear notification. If the investigation suggests formal disciplinary action might be needed, send the employee a letter setting out the allegations, the evidence and what happens next. Give them time to prepare.

4. Hold a disciplinary hearing. This is your chance to hear their side of the story. Make sure the hearing is structured and respectful. Remember, the employee has the legal right to be accompanied by a colleague or trade union representative (even if your organisation doesn’t recognise a trade union).

5. Make a decision based on evidence. Decide what action to take based on the seriousness of the misconduct and what you’ve learned from the hearing. Treat similar cases consistently to avoid claims of unfairness.

6. Communicate the outcome. Confirm the outcome in writing. If it’s dismissal, explain why. If it’s another form of disciplinary action, make expectations and timelines clear.

7. Offer the right to appeal. The employee must be given the opportunity to appeal the decision. This adds another layer of fairness and shows you’ve followed best practice.

8. Keep thorough records. Document every step – from the investigation and hearing notes to the final decision letter. This will protect you if the case is challenged later.
