I'm going to refuse to bring in a doctor's note for calling in sick.
Is it required to write a note? Then you don't have to if not. But I still no reason that you have to do it, you're not in second grade.
Why should I? My boss is so dumb. Why can't he just trust me?
I do think your boss should be a bit more trusting of you. Assuming you don't do this all the time, everyone should be allowed to call off sick every once in a while without having to go to the doctor and get a note.
Exactly! I rarely call out sick!
I think it's fine to stand your ground on this since you don't miss work often. It's not normal for bosses to require a doctor's note if you are sick. How an employee uses their sick days is their own choice.
