Happened to me.....I knew "they" were gunning for me...I stayed away from them as much as possible...did my work on time, was never sick, or late to work.
Covertly I worked against "them" as they were horrible mean-spirited lying cheating dirt-bags....Finally they all got fired..or asked to quit.
I outlasted them....but it still took a toll on me.
fwiw-
It’s always good to out last and out class the bastids then leave on your own terms. Good for you.
