I actually had to work with her on one thing and managed to control my worst impulses so it went okay. I survived.
But then the people in our sector had a call today with our boss and she was back to being irritating. The whole time she went between kissing my boss' butt and trying to tell everyone else what to do.
Maybe she should focus more on her own work. She consistently has by far the lowest production stats. People who do better than her have been fired or threatened with firing. I get the feeling she must be related to one of the higher-ups. That's the only explanation I can come up with.
