Suspending an Employee During an Investigation (UK): When It's Appropriate + A Practical SME Process

What Suspension Is (Plain English)

Suspension is when you tell an employee not to attend work (or not to do their normal duties) for a short period while you look into an issue—usually alleged misconduct, a serious complaint, or a situation where the employee's presence could affect evidence, colleagues, customers, or safety.

Important: Suspension is not the same as a disciplinary sanction. You're not saying "you're guilty". You're saying "we need space to investigate fairly."

In most cases, suspension is on full pay (unless your contract clearly allows otherwise, which is uncommon and risky).

When Suspension May Be Appropriate (And When It Usually Isn't)

Suspension may be reasonable if:

• There's a serious allegation (for example violence, serious harassment, theft, major safety breach).
• There's a real risk the employee could: interfere with evidence (delete messages, alter records), influence witnesses (pressure colleagues), repeat the alleged behaviour, or create a health and safety risk.
• The situation is highly sensitive and you need a short 'cooling off' period to stabilise the workplace.

Suspension is often not appropriate if:

• The allegation is minor and can be managed with normal supervision.
• You're using suspension as a 'default' because you feel uncomfortable.
• You haven't considered alternatives.
• You suspect the issue may relate to disability, pregnancy, whistleblowing, or a protected characteristic and suspension could look like retaliation or unequal treatment.
