Disciplinary action and investigations

Disciplinary action and workplace investigations are among the highest‑risk areas of UK employment law. Employers must act promptly and fairly, following procedures that stand up to scrutiny when decisions are challenged.

Poor investigations, procedural errors or inconsistent outcomes increase exposure to unfair dismissal claims, damaged employee trust and tribunal risk. Clear evidence, proportionate decisions and a structured process are essential.

This page brings together guidance and practical resources on disciplinary action and investigations—including processes, hearings and appeals—to help employers reduce risk and reach defensible decisions.
