I said I knew of two cases, both were consensual affairs, one of these people got a very high promotion that she didn't deserve as well. Relationship went south, guy got ugly about it, woman sued, woman got money. Gloria Allred, one of the foremost sexual harassment attorneys in this country was talking about it on television, if the man is in a superior position he will still be held at fault because it's not an equal power situation. You may be right about the points you made, as far as looking some definition up, but I am telling you that in those two specific cases, and these were high profile companies, the guy and the company were blamed.
I also worked WITH someone that was making out like a bandit and getting company cars, promotions, and all kinds of sh!t because of what she had going with our boss, but when she didn't want to play anymore she sued and got money. These cases didn't go to trial. Thank God because I was going to be deposed in the last example and didn't want to have anything to do with it.
I don't think tristan's wife should sue or anything! I'm just saying the fact that she was in a subordinate position DOES matter, especially because he is now harassing her for not wanting to continue the relationship. He's in deep sh!t if he keeps it up.
Documentation is important because people like her OM will smear the other person and lie their asses off. Plus it's just a matter of safety. You have to build a record of it in case it gets worse.
If she ignores him completely he will likely give up if he can't squeeze any attention out of it. But she needs to err on the side of caution.
