Suspension is a safeguard, not a sentence

When an allegation lands on your desk — a suspected theft, a serious breach of policy, a bullying complaint, a fraud concern — one of the first questions is usually whether to suspend the employee involved. It feels decisive. It protects the investigation. It shows you are taking things seriously.

But suspension is also one of the most frequently mishandled steps in workplace investigations, and it carries real legal and human risk. An employee who is suspended without good reason, or left suspended for months without explanation, may have a strong claim for constructive dismissal or breach of the implied term of trust and confidence. Suspension should be a neutral, temporary measure taken only when there is a genuine need — never a punishment, and never a way of signalling that you have already reached a view.

Ask whether suspension is actually necessary

There is no automatic rule that says an employee must be suspended while an allegation is investigated. In many cases, the investigation can proceed perfectly well with the person still at work. Before you suspend, work through the practical risks honestly.

• Risk to evidence: Could the employee destroy documents, delete records or tamper with systems? If so, can you remove access instead?
• Risk to witnesses: Is there a real chance they would pressure, intimidate or influence colleagues who need to give statements?
• Risk of repetition: Is the alleged conduct ongoing, or likely to recur before the investigation concludes?
• Risk to the business: Does the role involve handling money, safeguarding duties or regulated activity where continuing in post creates genuine exposure?

If none of those risks apply, alternatives usually work better. Consider temporarily changing duties or shift patterns, moving the person to a different team or site, adjusting reporting lines so they no longer report to someone involved, or agreeing a period of paid leave. Where the concern relates to system access, restrict permissions rather than removing the person. These options are less damaging to morale, less likely to be seen as a knee-jerk reaction, and easier to justify if challenged.

Where someone else is the complainant, think carefully too. A move should generally not disadvantage the person who raised the concern. Sometimes it is fairer to relocate the individual against whom the allegation has been made, but explain the reasoning and keep it under review.

Make the suspension decision properly

If you do decide to suspend, treat it as a decision that needs recording and reasoning. Identify who is making the call — usually a senior manager unconnected with the investigation — and note the specific risks that justify it. Confirm the terms in writing: whether the suspension is paid (in most UK cases it should be, unless the contract expressly allows unpaid suspension), how long it is expected to last, who the employee should contact, and what they should and should not do.

Set the tone in the letter and in the conversation. Use language such as "this is a neutral step while we look into the matter" and "no decision has been made." Avoid words like "misconduct" used as a conclusion, or anything that reads like a sanction. Explain what the employee can expect next and when they will hear from you.

Keep the suspension under review

Suspensions drift. A week becomes a month, a month becomes three, and nobody notices until the employee raises a grievance. Diarise a review at least every two to four weeks, and ask a simple question each time: are the risks that justified suspension still present?

• Has the evidence-gathering stage finished, so the tampering risk has gone?
• Can the remaining steps be done with adjusted duties or remote working?
• Is the investigation still moving at a reasonable pace, and if not, why not?
• Would a shorter, more limited restriction now achieve the same protection?

Record each review, even if the outcome is simply "suspension continues". If the delay is your fault — an investigator unavailable, a backlog, illness — acknowledge it and consider whether the suspension should end. Long unexplained suspensions are among the most common mistakes in workplace investigations, and tribunals look at them closely.

Communicate clearly and kindly

Being suspended is frightening, isolating and often humiliating, particularly if colleagues assume guilt. A little humanity goes a long way. Tell the employee who they can speak to, confirm they will receive updates, and make sure they can access support such as an employee assistance programme. Explain confidentiality expectations without implying they are being muzzled.

Brief the wider team carefully. You do not need to share the reason for the absence, and in most situations you should not. A short, neutral statement — that a colleague is away and their work is being covered — protects everyone, including the person under investigation. Remind those involved not to speculate, and make clear that the matter is confidential.

Keep witnesses and the complainant informed at a high level too, so rumour does not fill the silence. And once the investigation ends, communicate the outcome promptly and lift the suspension as soon as it is no longer justified.

Getting it right from the start

Suspension is sometimes unavoidable, and when it is genuinely needed it protects the integrity of the investigation and everyone involved. But it should always be the option you arrive at after considering the alternatives, not the default response to a difficult allegation. Decide on evidence, not instinct. Review it regularly. Communicate as though you are speaking to a colleague whose career and reputation matter — because you are.

If you are unsure whether suspension is proportionate, take advice early. It is far easier to get the decision right at the outset than to repair the damage of an unnecessary or overlong suspension later.
