First, I don’t take myself too seriously. I keep things light. With some folks I can get away with cracking a joke now and again, but I never laugh or crack a joke with people like this, unless it’s about myself, and so absurd, nobody can take it anything other than an obvious joke that means no harm.
If they are abusive, I document the behavior to the max. I also keep a very private diary of the interactions between me and the difficult person. (The paper trail is for the authorities, should things get out of hand.)
However, there is one time things did not go well at all. I got a new job, and the woman I was replacing (she had been promoted) set out to ruin my life. I tried to make friends, etc. but she was the favored one, and apparently could do no wrong (in spite of the fact that she was a felon, an ex-drug addict, had poor standards on just about everything). Anyway, things went along, and my boss just told me to ignore her or avoid her. That worked, until I had to put in my two-week notice. At that point, she escalated the abuse, and began to target me. One day she ran into me with the intent of knocking me down.
I complained to my supervisor. He told me he would not be allowed to do anything about the abuse, even though he sympathized with my problem. I finally called him up and told him I quit because I could not handle the stress, and I was concerned about getting hurt, my tires slashed, or whatever.
Apparently she is now the president’s “personal assistant”. It’s sick, because she talks like a trucker, and has no education.
