Nah, i'm not that dude that calls out of work and/or leaves early all the time. The dude I work with does it a whole hell of alot. So does the lady I work with. I swear, working overtime to them is like working 40 hours. They barely put in 40 while I put in 60 easy.
If i'm sick, i'll go in and try to deal with it. If it continues to get worse and I feel like I can't deal with it at work any more, i'll go home. Or if it's bad enough to begin with, I won't go in. To make money, you gotta work. I just wish my co-workers realized that.
