Even if you went and the guy didn't rape you, everyone would assume you slept with him to get any work or promotion you got after staying at his place.

Male boss asks you to dinner but doesn't ask anyone else? You are on the alert, uncomfortable and careful. Your boss thinks you are overly shy, too nervous and maybe not to be trusted.

Male boss sits next to you at dinner and grabs your leg? You are done for. Look for another job.

Male boss takes you on a business trip, takes a suite in a hotel with a shared bath, appears at your door dressed only in a towel? Watch out. You are being offered a promotion with strings attached. Look for another job

Attractive (not necessarily but apparently attractive enough) woman with a resume demonstrating academic excellence, personal recommendations suggesting good character and listing a lot of different workplaces -- may very well know what I am talking about.

Unless women sue over this kind of stuff and unless women who do sue are protected in that their names in the court records are sealed from public view, we will never have equality in the workplace.

Our discrimination (race, gender and age to start with) laws are written so as to permit the marketplace to punish the victims of discrimination who complain about their unfair treatment. Our very laws do too little to make discrimination in the workplace costly and unwise. We can do better.
