Frequently Asked Questions
- Can my employer suspend me during an investigation?
- Yes, if there's a genuine need - such as risk of evidence tampering, witness interference, or health and safety concerns. Suspension should be a neutral act, not a punishment, and kept as short as reasonably possible.
- Do I get paid during suspension?
- Usually yes. Unless your contract says otherwise, you should receive full pay during suspension. Unpaid suspension without contractual authority could be a breach of contract.
- How long can suspension last?
- There's no fixed maximum, but it must be kept under regular review and not last longer than necessary. Extended suspension without good reason can become a breach of contract or contribute to constructive dismissal.
