Your rights when raising a grievance at work

Filing a formal grievance is a protected legal process in the UK. Here's what you need to know.

The ACAS Code of Practice

Employers must follow the ACAS Code of Practice on Disciplinary and Grievance Procedures. If they don't, any employment tribunal award can be increased by up to 25%. Your employer must: acknowledge your grievance, invite you to a formal meeting, allow you to be accompanied, and give you a written outcome with the right to appeal.

Time limits — act quickly

Employment tribunal claims usually must be filed within 3 months minus one day of the issue. Before filing, you must contact ACAS for Early Conciliation, which pauses the time limit. Don't delay — a well-worded grievance letter now starts the clock on your employer.

Can I be dismissed for raising a grievance? ▾
No. Dismissing an employee for raising a protected grievance (especially relating to discrimination, whistleblowing, or statutory rights) is automatically unfair dismissal under the Employment Rights Act 1996. Keep records of everything and, if dismissed, contact ACAS immediately.
What if my employer ignores my grievance letter? ▾
If your employer fails to respond within a reasonable time (typically 28 days), this strengthens any future tribunal claim. Contact ACAS to start Early Conciliation, which is a free service and a required first step before an employment tribunal.
Do I need a solicitor to write a grievance letter? ▾
No. A clear, factual grievance letter submitted in writing is all that is required to start the formal process. Our AI generates letters that follow the correct format and reference relevant legislation. For complex discrimination claims or if you're considering an employment tribunal, it's worth consulting an employment solicitor or Citizens Advice.
