The ACAS Code of Practice on Disciplinary and Grievance Procedures sets out minimum standards. Failing to follow it does not make a dismissal automatically unfair, but tribunals can uplift compensation by up to 25%.

• Employer must investigate before any disciplinary action
• Employee has right to be accompanied at any hearing
• Letter must state the complaint, outcome, and right of appeal
• Warnings should state they are live for a fixed period
• Dismissal should only follow full procedure in most cases
