After some downsizing at my workplace, I was assigned to work alongside a co-worker on some year-long projects.
In past interactions, I knew she was struggling at the job, and she seemed honest about this. And management seemed content to have different expectations for her. But working closely with her on this project revealed to me just how over her head she was. I suspected she was nervous about working with me, because that would mean her work would come under greater scrutiny. I had no intention of informing management of anything, tried to acting as best as I could like I did not notice, and instead quietly offered to just work together on things.
But recently she has come to see me as a threat. She started sabotaging our projects, offering illogical explanations for her actions. Then I realized she was making up things, blaming the project's failure on me. Though I thought I'd carved out a respected reputation, management seems to think she's telling the truth. Her ability to project confidence in her lies outweighs my ability to express confidence in any conversation.
I cannot stop this person from telling lies about me to management behind my back. How can I protect myself from these attacks?
