I once worked with a gal who the perfect temporary employee. Then, they made her permenet. Suddenly, you had to give her a reminder that she needed to leave for her break in ten minutes, five minutes, you need to go now, please, you were suppose to leave for your break ten minutes ago. Well, gosh, but she's so busy doing her crossword puzzle. Trouble is, the rest of us couldn't take a break until she was done with hers! Anyway, she'd finally get up. go to the girls room spend ten minutes freshening up, take another ten minutes to reach the door, because she was compulsive talker and could never reach the end of her sentence. Someone would whisk her out the door and she'd go out to her car, drive home, and put her feet up on her couch for ten minutes before coming back to work, because, "it isn't a break unless I can put my feet up and we're not allowed to do that here."
Sadly, she's not the worse co-worker I've ever had to deal with. Got a story?
