When was the last time you called in sick? Was it just a case of the sniffles? Were you flat on your back? Or did you go golfing and not want to use a vacation day? Did you feel guilty about leaving your co-workers to cover for you? Did you take as few days as possible, knowing someone else had to pick up the slack in your absence? Chances are if you work in the private sector, your answers are very different from those of some government employees.
