I worked for one at a large corporation. She made one guy kill himself. Put another into a mental hospital. Publicly humiliated everyone in her group. Kept all our planned raises for herself and froze our salaries for three years. Gave everyone in her group a “5” (unsatisfactory; fire them). Made each of us sit in her office while she read our reports, sentence by sentence, making fun of them and scolding us (she couldn’t string two sentences together). Utterly irrational. Mad as a hatter. Got promoted. I was the only one in the group who fought her up to the VP level. Made her retract my 5 rating and rate me as “satisfactory.” VP of corporate ethics hired a PI and made him hide all her wrong-doing. Oh, yes; this was Digital Equipment Corporation on the way down to oblivion.
What a pity. Sounds like her tenure was in order to do someone a favor.
