Two separate processes
Your data request runs separately from the grievance. The grievance doesn't pause the deadline for your request, and your request doesn't delay the grievance. The Acas Code of Practice on disciplinary and grievance procedures sets out how a grievance should be investigated and heard.
What to ask for
- Notes of grievance meetings and investigation interviews
- Witness statements that mention you
- The investigation report and outcome letter
- Emails and chat messages about your grievance, including between managers and HR
Witness statements
Statements usually contain other people's information. Your employer can black out details that identify a witness unless they agree, or it's reasonable to share them. What's said about you is still your data, so you'll often get the substance with names removed.
What else can be held back
- Communications between your employer and its lawyers are covered by legal privilege and don't have to be disclosed.
- Records of your employer's intentions in negotiations with you, such as settlement talks, can be held back while sharing them would harm those negotiations.
What to put in your request
- Grievance meeting notes
- Investigation interview notes
- Witness statements about you
- The investigation report
- Emails between managers and HR about your grievance
