How much is too much? I'm trying to be as conscientious as possible about this, and always feel guilty whenever I call in. I work in health care and have had this particular job for 6 months. I've called in three times so far - two were just for a day when I was having excessive gut symptoms, and a third was when I had the flu and took the week off. I feel like I need reassurance that this is reasonable. How often do you call in?
