Using WhatsApp messages in a work dispute

Practical guidance, not legal advice. Rules differ by country and court. Your lawyer has the final word.

Shift changes, instructions, comments from a manager, a group chat that turned hostile: workplace WhatsApp messages often end up in grievances, disciplinary hearings and employment tribunals.

Before you do anything

• Only use chats you were part of. Don’t take screenshots from other people’s phones.
• Check your employer’s policies and ask your union rep or lawyer what you may share and with whom.
• Export early. You may be removed from a work group, and then the history is harder to get.

Exporting a work group chat

Group chats export exactly like one-to-one chats (iPhone · Android). In Paperthread, every sender gets their own colour, and the Records layout lists each participant with their message count on the cover page.

Presenting it

1. Choose the Records layout and filter to the relevant dates.
2. Use a page-reference prefix (e.g. C- for claimant documents) if your adviser suggests one.
3. Keep the original export file, and note the SHA-256 fingerprint printed on the cover page.
