You tell me.
If a woman's right to choose includes prostitution, does it also include being able to turn away customers based on their race?
Not if it's legalized.
If she's running a legal business, she's subject to the rules and regulations of all other businesses.
Which means that the job requirement "you must have sex with your clients" would rule out quid pro quo sexual harassment.
Well, if that's to be interpreted as "you must have sex with all your clients or else you're fired, and I decide who's a client", that doesn't rule out quid pro quo sexual harassment; that
is quid pro quo sexual harassment. The job requirement "you must type and take dictation and bring coffee and have sex with the boss's wife while he watches or else you're fired" is a perfectly possible job requirement too, and that doesn't make it rule out quid pro quo sexual harassment. Some job requirements are intrinsically harassing.
The entire sentence was:
Which means that the job requirement "you must have sex with your clients" would rule out quid pro quo sexual harassment. You would only be able to apply that standard in situations where a legal prostitute was being pressured to have sex with someone who WAS NOT a paying client under threat of losing her job.
These are not separate things. "You must strip naked in front of our customers" is a job requirement of being a stripper. But strippers being forced to strip for people who are not paying customers does, in fact, count as sexual harassment. Forcing strippers to give private shows they are not being paid to give is as well. You can fire a stripper for refusing to strip for a paying customer, IF it's understood that she is refusing to do something she previously agreed to do in her contract.
But if I found myself in the regulator-of-legal-prostitution job, I'd have no trouble applying the quid pro quo sexual harassment standard to situations where a legal prostitute was being pressured to have sex, even with someone who was a paying client.
You would, actually, because there's already quite a bit of precedent covering this in the porn industry and other forms of adult entertainment. There's enough case law from legal prostitution in Nevada that sexual harassment is fairly closely associated with client-worker relations, the responsibilities of the client, the responsibilities of the employee, and the responsibilities of the employer/facilitator. Among other things, a facilitator cannot deliberately expose his workers to physical abuse, nor can he require them to place themselves in situations where a risk of bodily harm is likely (e.g. having sex with a guy who admits to being HIV positive or states his intention to strangle one of the girls during sex). This is different from
sexual harassment, which SPECIFICALLY refers to unwanted sexual advances unrelated to the job requirements or not consented to in any prior contractual agreement or job description. The law also makes it clear that there is (and pretty much by definition, MUST BE) a difference between a paying customer and anyone else that woman might have sex with, voluntarily or otherwise. While a facilitator can definitely fire a girl for refusing to have sex with paying clients, he is ALSO liable if he allows the client to force himself on her even after she refuses; raping a prostitute is still rape whether you paid her first or not.
If he didn't force her and merely stiffed her afterwards
Probably a good idea in theory; but in practice insisting on written contracts would probably wipe out most of the market since there's a stigma to visiting prostitutes, and most johns aren't going to want there to be that kind of proof that they did it floating around.
Removing the illegality of it would take care of a lot of that. Confidentiality is already a given for dating websites and porn subscriptions.
