What is a Sick Leave Message?
A sick leave message is a short text you send to inform your manager or team that you are unwell and will not be able to work.
Key differences from email:
- Message (text/chat): short, quick, direct
- Email: formal, detailed, structured
When to use it:
- Early morning call-ins
- Sudden illness
- Remote work updates
- Informal workplace communication
If your workplace uses messaging tools, a short sick leave text is often completely acceptable.
