Grievance Before Resigning
Why you should usually raise a grievance before leaving.
Last updated 21 February 2026
Overview
While not a strict legal requirement, failing to raise a grievance before resigning for constructive dismissal can result in a tribunal reducing your compensation by up to 25%.
What you can do
- Submit a formal written grievance detailing the breach of contract.
- If the employer ignores it or fails to resolve it, this can constitute a 'last straw' justifying resignation.
