Ok lets get this straight. There is a difference between calling off and "calling off". You can call off ahead of time and schedule your vacation day or sick day if need be. Now there is a difference between that and calling off at 6am when you are supposed to be at work at 7am.
I'm pretty sure i have a "real" job. Benefits, stock options, 2 raises a year, paid vacation sick and personal. health care. etc..
