Sleep with the boss to get the job?

My friend Ann worked at I-Bank as an intern. She told me that most women there took pride in being able to get a high up to sleep with. The more powerful the better. One woman is elated when the married managing director only goes out with her for the moment. And everybody is kissing her ***. Ann is pretty and however she is not a loose woman. After she rejected her managing director, who picked her up as if she is a stripper in the bar, other guys start to advance on her: some said she should have gone out with the MD so she doesn't have to subject to other minions. And her time there would be much easier and may even have a job offer. She do not feel like compaining because it seems women sleep with bosses is a common practice there. Ann told me maybe she should have slept with the boss, though married, but seems really like her.
