FettsBabe: Your description of sexual harrassment missed probably the most important aspect of current law and that which is most often litigated (you imply it, I think, but don't use the "catch phrase"

: "hostile work environment". Fortunately, recent decisions in US appellate courts (two that I read a couple months ago) have restricted the doctrine a tad and raised the bar a little higher for the plaintiff to prove the "hostility". However, the arguments surrounding pictures, jokes, lewd actions and such all encompass this aspect of harrassment as opposed to the "quid pro quo" of trading sex either for job security, a raise, or avoidance of disciplinary action.
Personally, I think the entire canon of harrassment law has merely served to chill workplace relationships between men and women and has adversely affected women in the workplace. While I am certainly in favor of ending the quid pro quo aspect, the "hostile work environment" just gets ridiculous at times. Since the lines are so fluid as to what is and is not harrassment under the vague guise of "hostile work environment", employers are forced to be absolutely draconian in their approach to male/female interaction -- I wouldn't be surprised to see segregated companies in the near future (men in this building, women in this one). If you compliment someone for the way they look (innocently enough and in a polite and decent manner), you can be warned or even fired if they really felt like strictly adhering to their policies. I have a picture of Natalie Portman as my desktop wallpaper, and my boss (a woman) commented on it -- it's absolutely tasteful with the only skin showing being her face and hands! Why that should even remotely enter the realm of question is beyond me (I still have it up and will not take it down, wasn't asked to).
My mantra is that the legal system lacks common sense. There is no
justice in our justice system -- it's obssessed with technicalities and obscure rules and procedures so that the monopoly of the legal profession is maintained. Keep it opaque, and you need lawyers. Make it simple and straightforward, and suddenly lawyers are not so important anymore.
And people wonder why laws get more and more bizarre every year.
