Mine is people having personal conversations (and not trying to hide it) and sleeping!!! I get personal calls too, but I can also work. I know that those other people are just sitting there talking!
A couple of weeks ago, this one chick was out all week sick. Then when she came back she slept half the time because she didn't feel well. I asked why doesn't she go home. Her response, "I don't have any more sick time."
I thought too d___ bad. It's not fair that she gets paid for sleeping. Plus, she got caught by the Manager and he didn't say anything!

Had been me or the other girl on my team, we would've been out of there!
