The problem with HR is that their job is to protect the company interest. HR is not your friend and not an advocate for the employee. So if HR thought that she was more valuable to the company even if she was in the wong they could twist so I was in the wrong. I've seen this happen too many times. The only way I could be sure of a favorable, unbiased outcome with HR is to get a video recording of her behavior so there is no disputing fault. Once I had a video, I would go to my Boss first if that didn't work then HR.

What can a company do really if an employee is being a brat? Are there any laws being broken for being rude and curt to other employees? What grounds do I have for a case?
