Raising a grievance
How to raise concerns at work in a way that protects your position and builds a paper trail.
Last updated 8 February 2026
Overview
A grievance is a formal complaint to your employer about a workplace issue.
Handled properly, it creates a clear record and can resolve problems before legal action.
When to raise one
- You want to challenge unfair treatment or a decision.
- You need the employer to correct behaviour or process failures.
- You are preparing for a possible claim and need a clear record.
- You tried to resolve the issue informally and it did not work.
How to structure it
- 01
State the issue
Open with a short summary of what happened and when.
- 02
Explain the impact
Describe how it affected your work, health, or income.
- 03
List evidence
Reference key emails, meetings, or documents.
- 04
Request a remedy
Say what outcome you want, such as a meeting or correction.
- 05
Keep it factual
Stick to dates and facts so it is easy to investigate.
What happens next
- The employer should acknowledge the grievance and appoint someone to review it.
- You may be invited to a meeting to clarify facts or respond to questions.
- A written decision should follow, with the option to appeal.
Evidence to attach or reference
- Key emails or messages
- Schedules or rota changes
- Policies that were not followed
- Names of witnesses
- Medical notes or fit notes if relevant
Common questions
Do I have to finish the grievance before ACAS?
No, but completing the process can help show you tried to resolve it internally.
What if the employer ignores my grievance?
Follow up in writing and keep the record; lack of response can still be relevant.
Can I raise a grievance while off sick?
Yes, you can submit it in writing and request reasonable adjustments.
