Is it acceptable to ring in sick because you feel too exhausted to function?

Yes, you can catch the flu and other things easier if you get run-down tired. Then spread it to others and they'll be sick for a week or more.

Yes!!!! You honestly feel like you would be a liability to the workplace? Go for it. Make something else up though...

Yes, you could get a cold or flu (or might be starting to get one, causing you to feel that way), or you could just be exhausted and unable to function properly. Just tell them you don’t feel well....you don’t need to gie them a long explanation.

You betcha. I do it a lot. I can because I have my own business and only work on nice days.

Sounds like a legit reason to me.
