About Workplace Grievances

A formal grievance letter raises a workplace complaint with your employer under the ACAS Code of Practice on Disciplinary and Grievance Procedures. Sets out the issue, evidence, and what you’re asking for: a foundation document if the dispute later escalates to an employment tribunal.

Frequently Asked Questions

Who should I send the letter to?

Your line manager, or HR if the grievance is about your manager. Follow your company’s written grievance procedure if one exists.

What should the letter include?

Clear statement of the issue, dates and evidence, any witnesses, what you’d like as a resolution, request for a hearing under the ACAS code.

Does my employer have to respond?

The Acas Code of Practice on disciplinary and grievance procedures (published 11 March 2015) is the minimum an employer should follow. Acas states that the procedure an employer follows, and an employee's actions, will be taken into account if the case reaches an employment tribunal. Acas issued a draft updated Code for consultation on 30 July 2026; the current Code still applies.
