Workplace grievance procedure UK

Step 1 — Informal resolution

• Speak to line manager directly
• Or HR / employee assistance service
• Aim for resolution without formal process
• Note the conversation for record

Step 2 — Formal written grievance

If informal doesn't resolve: - Write to employer stating grievance - Include: specific issue, evidence, desired outcome - Follow employer's grievance procedure - Employer must acknowledge + progress

Step 3 — Investigation

Employer investigates: - Interviews with relevant parties - Review of documents / evidence - Reasonable time (typically 2-4 weeks)

Step 4 — Grievance hearing

• Employer invites employee to hearing
• Right to be accompanied by colleague or trade union rep
• Reasonable time to prepare
• Employee presents case
• Employer responds

Step 5 — Written outcome

• Employer's decision in writing
• Reasons for decision
• Any actions being taken
• Right of appeal + how to exercise

Step 6 — Appeal

• Employee may appeal in writing
• Appeal heard by different manager (typically more senior)
• Appeal decision final within employer's process
• After appeal: external routes (ACAS, tribunal)

Post-appeal options

• ACAS Early Conciliation
• Employment tribunal for actionable claims (unlawful deductions, discrimination, unfair dismissal)
• No tribunal for pure grievance without underlying legal right

ACAS Code uplift

Tribunal can adjust compensation: - Up to 25% increase if employer unreasonably failed to follow ACAS Code - Up to 25% decrease if employee unreasonably failed

Common employer failures

• No formal written procedure
• Delayed investigations
• Predetermined outcomes
• No right of appeal offered
• Retaliation for raising grievance

In short

ACAS Code: informal → formal → investigate → hear → outcome → appeal. Non-compliance = 25% tribunal uplift.
