Gross Misconduct Suspension Letter

The Gross Misconduct Suspension Letter is used where an employer needs to suspend an employee while allegations of gross misconduct are investigated. It is for serious cases where the alleged conduct may justify summary dismissal, but the facts must first be properly established.

Gross misconduct will usually involve very serious wrongdoing, such as:

- theft or fraud;
- violence, assault, or threats;
- serious harassment or discrimination;
- deliberate or reckless health and safety breaches;
- damage to property or gross negligence; or
- breach of confidentiality or data theft.

Even where the allegation is serious, dismissal should not take place without a full and fair investigation.

When suspension may be appropriate

This letter should be used where the employer considers suspension necessary while investigating suspected gross misconduct. Suspension is a precautionary step, not a punishment.

It may be appropriate where there is a risk that the employee could:

- interfere with evidence;
- influence witnesses; or
- create a risk to staff, property, or business operations.

Suspension should still be a last resort. Where the issue can be managed another way, such as changing shifts or restricting duties, those options should be considered first.

Keeping the suspension neutral and proportionate

A gross misconduct suspension must be handled carefully. The letter should make clear that the suspension is precautionary and neutral, and not a disciplinary sanction or an assumption of guilt.

It is for the employer to decide, acting reasonably, whether the alleged conduct could amount to gross misconduct. The Disciplinary Procedures and Policy includes a non-exhaustive list of matters the company will normally treat as gross misconduct.

What the suspension letter covers

The letter provides formal written confirmation of the suspension. It also confirms that pay and benefits will continue during the suspension period.

It sets out the main restrictions that apply, including that the employee must not contact colleagues, customers, or suppliers without permission.

The next step depends on the outcome of the investigation:

- if the investigation indicates gross misconduct, a disciplinary meeting should be arranged; or
- if it does not, the suspension should be lifted.

If a disciplinary meeting is required, see the Gross Misconduct Disciplinary Meeting Notice.

Fair process and ACAS compliance

Gross misconduct cases require a fair and reasonable procedure throughout, particularly where the outcome could be summary dismissal without notice or payment in lieu of notice.

For broader procedural guidance, see the Disciplinary Procedure Guidance Notes alongside the Disciplinary Procedures and Policy.
