<human>: Hey guys, I work closely with another manager in my department (we are both managers - I recently was promoted to the position) and I know for a fact that she badmouths me to employees (the people I am supposed to be accountable to/for.) and has recently taken to sabotaging me at work. I have already expressed my concerns to the GM and director of operations, and filed a complaint because before I even started the position she had been trash talking me to other employees. So far, she has hidden supplies that I need to do my job, changed standard operating procedures behind my back, and changed the password to our shared notebook (which has documents and backups I need to do my job)... I don't know what to do at this point. I want to take the higher road and just talk to her and tell her she needs to get her act together but I have confronted her before and she always has a convenient excuse. Another part of me wants revenge. Any ideas for me?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My coworker is trying to sabotage me at work. Need a "creative" solution for  how to deal with her.
