Dear [Recipient name],

RE: FORMAL GRIEVANCE — [one-line subject, e.g. "treatment by [name]
between [month] and [month]"]

1. I am writing to raise a formal grievance under the organisation's
   grievance procedure and the ACAS Code of Practice on Disciplinary and
   Grievance Procedures.

2. THE FACTS
   Set out what happened in date order. One paragraph per incident:
   - On [date], [who] [did/said what], at [where], witnessed by [names].
   - On [date], ...
   Quote exact words where you can. Attach or reference documents:
   "see email of [date], enclosed at Appendix 1".

3. WHY THIS MATTERS
   State the policy, contractual term or legal duty you believe has been
   breached, e.g. "I believe this treatment is [related to my disability
   within the meaning of the Equality Act 2010 / a breach of the duty of
   trust and confidence / contrary to the dignity at work policy]."

4. IMPACT
   Brief, factual: effect on your health, work, or working relationships.

5. THE OUTCOME I AM SEEKING
   For example: an independent investigation; specific action in respect
   of [name]; a review of [decision]; an apology; confirmation in writing
   of steps taken to prevent recurrence.

6. PROCESS REQUESTS
   Please confirm receipt in writing, the name of the grievance manager,
   and the date of the grievance meeting. I intend to exercise my right
   under s.10 Employment Relations Act 1999 to be accompanied by
   [colleague / trade union representative].

Yours sincerely,
[Your name]
