Keeping Evidence and Logs
How to evidence your grievance for tribunals.
Last updated 21 February 2026
Overview
If your grievance ends up in a tribunal, the outcome often depends on 'contemporaneous evidence'—records made at the time the events happened.
A private diary or log is much more persuasive than trying to remember dates months later.
What you can do
- Keep a log of dates, times, locations, and witnesses.
- Forward non-confidential evidence (like threatening emails or changed rotas) to a personal account, being careful not to breach GDPR or company policy.
