How to Email Your Boss About A stomach bug
When your workplace expects things in writing, a short email about a stomach bug keeps a clear record. Put the key facts up front.
Say what you need, briefly
A stomach bug can be contagious, so heading home is sensible. Keep it brief and non-graphic; that you're unwell and would rather not spread it is the point.
Structure it as a short email
In an email, lead with a plain subject line, put the day and leaving time in the first line, add one line on how your work is covered, and keep a courteous sign-off. An email should be shorter than a chat message, not longer.
Example messages
Subject: Leaving early. Hi [Manager], I'm unwell and would rather not risk passing anything on. I'll head out by [time]. Thanks, [Name].
Subject: Leaving early. Hi [Manager], Not able to keep working with this bug — I'll log off by [time] and follow up tomorrow. Thanks, [Name].
Mistakes to avoid
Don't write a long paragraph or bury the ask. Put the day and leaving time in the first line so it's seen at a glance.

Common questions
How much should I say?
Very little. A stomach bug and needing to go home is complete.
Email or a quick message?
Use email where a written record is expected; a chat message is fine elsewhere.
