The two most important things to understand, imho, that I don't see mentioned here are the line between professional and social situations and the different between power and peer.
Some the behavior in the news is inappropriate in any situation, but rises to the level of formal complaints/charges/losing a job, etc. because it is done is a professional situation. If you are at work, keep the conversation PG and you won't have any problems. It's very simple. Don't try to get laid at work. The same behavior Saturday night at your local watering hole/nightclub/bar is very different in the conference room on Monday morning.
Especially don't try to get laid at work if it is someone you have power over (directly or indirectly). That will never end well. Just not worth it. It doesn't matter whether you are making it a condition of employment/promotion/raise/whatever, it isn't fair to put someone in a situation that could be interpreted that way even subliminally.
Burkas have been mentioned. The reason for the burka culturally is the belief that men can't control themselves around a beautiful woman (or any woman not covered head to toe), so unless she covers herself completely, whatever happens is her fault. All the comments about how women dress, that she's "asking for it, etc" is rooted in that same belief, which I personally believe is BS. Men have self control. Some choose not to exercise it. Women should be free to dress however makes them feel good/beautiful/professional/whatever, and men need to learn to coexist respectfully and behave appropriately; just like you need to control yourself walking into a store and not just taking whatever you want, entering a candy store and eating everything on the shelf, not strangling that other contractor that f-ed up your job, etc. Self-discipline and impulse control is just part of growing up. Unfortunately some never did and need to learn those skills vs the rest of the world accommodating them.
The policy referenced in the OP is just the corporate version of a burka; accepting that men can control themselves, so the women need to change to accommodate that. It's sad.
