Just remembering how awful boss got so into building a team and mentoring her team members that she was uncomfortable and weird about my teaching because she couldn't ignore that I was good at it even when I was struggling, and that I had two decades of experience doing that kind of teaching, and that I built rapport very quickly because I'm genuinely good to people. She was so displeased that she couldn't box me in about it like she could with other things.
I know I'm far from the first to be abused out of a job by a manager who wants to change things to favor their own authority and sideline preexisting expertise, but it's still really damaging to experience it and sometimes I have to grieve it real hard, still, but other times it feels like I made it up and it can't possibly be true. I hate that. I know this is how workplace abuse can go, but it is so wasteful, and so ridiculous, that it also seems unreal at times, and yet I have the PTSD.
