I have a friend from work that takes a lot of sick days. He works the full time assistant position at the job where I work as a part time student employee. He takes a lot of time off because he finds the job emotionally overwhelming and I'm beginning to think that he might have depression. Heck, I'm the one who encouraged him to use his sick/leave days liberally on days that I'm there so I can cover for him.

Point being lots of people take sick days for lots of different reasons. In fact, I would suspect that most people take sick days off for any other reason but being physically sick, especially if a job is high stress/pressure. Lots of people, particularly those from older generations, seem to be against people using sick days like that.

So yeah, don't take offense to it.
