I often work alone w/ my supervisor (no witnesses) & she'll bully me harshly by negating everything I do & implying I'm not doing a good enough job. She's cunning & manipulative in the way that she knows if I repeat it to anyone else she can say she's looking out for the best interest of our program. Last time I spoke to HR they took her side. She does it b/c she wants me to quit but I don't want to. A monkey could do my job. What can I do? Record convos? Sorry for this question.
In many places it is a crime to secretly record conversations. So be careful about that. Here is what you do, and I know you aren’t going to like this advice but you need to step back and ignore her. That’s right. The way things are now she holds all cards and push come to shove and it is your job on the line. So, avoid open confrontation. Ignore her unprofessional comments. Accept any legitimate advice (she is your supervisor after all) and kill her with kindness.
This how you deal with a bad manager if you want to keep your job. If you don’t want to keep your job then quit on your own terms after you first find another position.
