Hey, I'm not feeling well today. I think I need to take a sick day. Sorry for the short notice.

Use when notifying about sudden illness.

I woke up with a fever and a terrible headache. I don't think I should come in today.

I'll try to check my emails from home if I'm feeling up to it, but I might need the full day to rest.

I've already handed off the urgent stuff to Sarah. She knows what needs to get done.

The report is mostly done. I'll finish it up as soon as I'm back, probably tomorrow.

No worries, take care of yourself. Just keep me posted if you need another day.

Manager reassures and asks for updates.

That's fine. Just make sure to submit the sick leave request in the system when you can.

Get some rest. Don't worry about work — we've got it covered.
