Dismissal for gross misconduct

This is a question that comes up very often, and the short answer is yes, you can dismiss someone for gross misconduct without notice, but only if you follow a fair process first. The idea that gross misconduct means you can sack someone "on the spot" without any procedure is one of the most common and dangerous misconceptions in employment law.

The legal position:

Under the Employment Rights Act 1996, an employee with two years' continuous service has the right not to be unfairly dismissed. Even where the reason for dismissal is gross misconduct, the dismissal must be both substantively and procedurally fair. This means the reason must be sufficient and the process must be reasonable.

Gross misconduct entitles you to dismiss without notice or payment in lieu of notice. That is what "summary dismissal" means. It does not mean you can skip the disciplinary process.

What you must do:

1. Suspend the employee on full pay if necessary while you investigate. Suspension should not be automatic or punitive but should be considered where it is genuinely needed, for example to preserve evidence or protect other staff.

2. Carry out a reasonable investigation. Gather evidence, take statements, review documents. The investigation must be proportionate to the allegation.

3. Invite the employee to a disciplinary hearing in writing, setting out the allegations clearly and enclosing the evidence you are relying on. Give them reasonable notice of the hearing.

4. Hold the hearing, allowing the employee to state their case, ask questions, and be accompanied by a colleague or trade union representative under section 10 of the Employment Relations Act 1999.

5. Consider the evidence and the employee's response before reaching a decision. The decision-maker should ideally be someone who did not carry out the investigation.

6. If you decide to dismiss, confirm this in writing with reasons and inform the employee of their right to appeal.

7. Offer and hold an appeal if the employee requests one, ideally heard by someone more senior who was not previously involved.

The ACAS Code of Practice on Disciplinary and Grievance Procedures is the key reference here. It does not have the force of statute, but employment tribunals are required to take it into account, and an unreasonable failure to follow it can lead to an uplift in compensation of up to 25 per cent.

Common pitfalls:

Dismissing on the spot without any process is the single biggest mistake employers make. Even if the misconduct is clear-cut, a tribunal will very likely find the dismissal procedurally unfair if no proper process was followed.

Another common error is treating suspension as a punishment or as an automatic step. The ACAS guidance is clear that suspension should be brief, kept under review, and only used where there is a genuine reason for it.

Failing to investigate properly, or having the same person investigate and decide, also creates risk.

Practical considerations:

If you genuinely believe gross misconduct has occurred, you are within your rights to suspend the employee immediately on full pay and begin the disciplinary process straight away. In urgent cases the whole process can be completed quickly, sometimes within a matter of days, but it cannot be skipped entirely.

If the employee has less than two years' service, the risk of an ordinary unfair dismissal claim is much lower because they generally lack the qualifying period to bring one. However, even in that situation there are risks. The employee could still bring claims for automatic unfair dismissal, wrongful dismissal, or discrimination, none of which require two years' service. Following a fair process is therefore good practice regardless of length of service.

If you want to proceed, the sensible approach is to check your own disciplinary policy, follow the ACAS Code, document everything carefully, and make sure the process is fair, reasonable, and timely.
