In your district you get three personal days per year, and you have already earned all three. You would like to go out of town for a long weekend with some friends and would need to take Friday off to do so. Is it ethical to call in "sick" for this day even though you are not actually sick?
I agree take it off as a personal day, then there are no question of ethics.
I also agree, just take a personal day.
I think it was mentioned that all 3 personal days were taken already.
It is not worth losing you job over, so I say personal day is most appropriate.
I think he should just be honest and say he needs to take a personal day. Save the sick days in case you need them
