I ask as I start my volunteer position at a well known non-proft and my current boss at my current fulltime job is extremly manipulative

. I'm curious if I should look out for such a boss in a volunteer position
Quick story:
She has tried to take advantage of the fact that I have Aspergers. She told human resources that some employee who I got along with was bullying me(She doesn't like him for some reason). I NEVER said anything to her regarding the issue. It caused a lot of problems for me, eventually it got sorted out by human resources. She was able to cover her ass, before trying to blame the whole situation on me. Now, I get along with that co-worker, and no one lost their job(including her sadly).
How common are people like this in IT? I know there are manipulative workers/bosses everywhere, but do they go to this level? I found this to be an all time low. I did nothing to my boss, and I do my job well and show up on time. Yet, she tried to use me as a pawn to try to get rid of another worker?
