ACAS Code of Practice on Disciplinary and Grievance Procedures

The statutory code under section 199 Trade Union and Labour Relations (Consolidation) Act 1992 setting out fair process for workplace disciplinaries and grievances. Tribunals can adjust unfair dismissal awards up to 25% for unreasonable failure to comply.

The ACAS Code is the framework for fair workplace procedures. It requires: written notification of issues; right to a hearing with companion; investigation; written outcome; right of appeal. The Tribunal can uplift compensation by up to 25% where the employer unreasonably failed to comply, or reduce by up to 25% where the employee unreasonably failed. ACAS produces detailed guidance to accompany the Code. Other ACAS Codes cover Settlement Agreements, Flexible Working, Time Off for Trade Union Activities, and Dismissal and Re-engagement (the 2024 fire and rehire code).
