we both work for the same company and when a new position became available we both applied, they hired me not her. Because I was a team player and she was always talking back to the other employees. Now she is trying to sabotage me by bringing up my errors when ever management is around. There have been complaints of her before, so how do I protect myself from keeping her from making me look bad. Everyone at the office gives good feedback about my work except for her. what can I do? What do you call this type or person?

Backstabber. Just keep doing a good job and you will have no problem. Don't stress out.

A backstabber. Keep your cool. Your in the right. If it becomes too bad complain. Don't suffer because someone is ill mannered.
