How Do I Correctly Dismiss Someone for Gross Misconduct Without Ending Up in a Tribunal?

Few situations are more stressful for employers than dealing with gross misconduct. It’s serious, it’s urgent, and it can have a big impact on your team and business. But acting too quickly – or skipping steps – is the fastest way to end up in a tribunal. The key to minimise the risk? A fair, structured process.

Below, we outline the steps you need to take to protect your business and handle dismissal correctly.

1. Start with a full investigation

Even in cases of gross misconduct, you cannot skip straight to dismissal. You need to:

• Investigate thoroughly: Gather all the facts before making any decisions.
• Consider suspension: If necessary, suspend the employee on full pay while the investigation takes place.
• Hold an investigation meeting: make sure you take clear notes of what’s said and seek to find evidence and clarity of the circumstances from all perspectives.

2. Escalate to a disciplinary hearing

If your investigation confirms that there is a behaviour that needs to change, the next step is a formal disciplinary process:

• Provide at least 24 hours’ notice of the hearing.
• Allow the right to accompaniment (a colleague or trade union representative).
• Document everything: From the invitation letter to the outcome.

3. Keep the process fair and impartial

The most important rule? Never start with a preconceived outcome. Even if the evidence seems clear, the process must remain fair and unbiased. This protects your business and ensures compliance with employment law. Decisions should be reasonable with dismissal as a last resort.

The key takeaway

Dismissal for gross misconduct is serious and so is the risk if you get it wrong. The safest approach is to:

• Investigate fully.
• Follow your disciplinary procedure and ACAS best practice to the letter.
• Document every step.
• Avoid assumptions or shortcuts.
• Dismissal should be a last resort.

Handled correctly, this approach protects your business and reduces the risk of ending up in a tribunal.
