My current boss is lovely, amazing, kind... and a man!
My previous boss was also a man, but completely inept.
My boss before that, a woman, who had had to climb the greasy pole through ad agencies in the Thatcher era. Nuff said. . I got on OK with her, in fact she LOVED me, but I was (secretly) terrified of her. While she was really quite inspirational she also had a totally irrational, prima-donna like attitude that spat people out when they'd outlived their usefulness.
My boss before that was a man who was a complete wanker of the highest order. I would still like to smack him round the back of his smug bonce with a serious piece of Le Creuset Ironware.
When I did temping work as a student I worked for a complete bitch who told me to go home after a week because I was basically useless. In front of everyone and in the most horrible way. Had me in tears. But I think it was because her long-term dp (not her choice apparently ) fancied me. He worked in the same office and was always very nice to me.
I think a lot of women are fine to work for until they feel threatened.
I think I'm a really nice boss myself ... my colleagues may think otherwise though!
