Uh... nobody. There was one person once who stalked me and tried to sabotage me, but they're gone and I'm not. It started with her getting hired and trying to pawn off all the worn on me while taking credit for it, trying to make it look like I would leave early, and talked all sorts of shit about me to my boss at the time (who also no longer works here).

I documented everything they did, excelled at my job, make friends with everyone, and built up my reputation: I got promoted and they became unemployed after becoming a pariah when people caught on to what was actually happening.

Document everything, nail it when it comes to your responsibilities, and try to maintain a good relationship with everyone, but at the end of the day if the above doesn't work it's not just a problem with your bully, it's a problem with your workplace in general and it's time to find something better: Polish up that resume and find a place that treats you right!

Life is too short to allow yourself to be abused for money.
