Grievance letter builder
Answer a few questions and get a formal grievance letter in your own words, set out the way the Acas Code of Practice expects. Stick to facts: what happened, when, and who was there. Nothing you type leaves your browser, and nothing is saved when you close this page.
Your letter
Before you send it: check every date and fact, keep a copy, and note when you sent it. Raising a grievance does not pause tribunal time limits, so if you might bring a claim, work out your deadline now. Read the grievance guide for what happens next.
