I worked with a woman who did this on a regular basis. She had 2 men fired for "sexual harrassment" when she was the one who would flaunt herself and sit on their desks. Her (and my) boss was terrified of her and what she might do to him. So everytime I got a bonus for doing a great job on a huge project, she got one too for no reason at all, other than the boss being afraid of her.
I'm not saying it doesn't happen. But there are women who make it worse for us good women. She took advantage of the situation and got good men fired for no reason, other than the fact she was trying to get in good with our very corrupt HR manager, who 2 yrs later was actually walked out by security!
