Well, I would hope she would have rights as any other worker. I would not want her to be arrested as "pimp" or "brothel owner" for working together with a friend to create protection.
Most "Other workers" don't need to work with someone else to protec themselves form rape 
No one on this thread wants to criminalize prostituted women from what I can see. So your whining about feminism trying to make them vulnerable to police etc is a bit ridiculous. Personally I hope my daughter is never involved in a "profession" where her being raped or being on the receiving end of physical violence is almost assumed. I hope you haven't got children.
"About 80% of women in prostitution have been the victim of a rape. It's hard to talk about this because..the experience of prostitution is just like rape. Prostitutes are raped, on the average, eight to ten times per year. They are the most raped class of women in the history of our planet. " (Susan Kay Hunter and K.C. Reed, July, 1990 "Taking the side of bought and sold rape," speech at National Coalition against Sexual Assault, Washington, D.C. ) Other studies report 68% to 70% of women in prostitution being raped (M Silbert, "Compounding factors in the rape of street prostitutes," in A.W. Burgess, ed., Rape and Sexual Assault II, Garland Publishing, 1988; Melissa Farley and Howard Barkan, "Prostitution, Violence, and Posttraumatic Stress Disorder," 1998, Women & Health.)78% of 55 women who sought help from the Council for Prostitution Alternatives in 1991 reported being raped an average of 16 times a year by pimps, and were raped 33 times a year by johns. (Susan Kay Hunter, Council for Prostitution Alternatives Annual Report, 1991, Portland, Oregon) 85% of prostitutes are raped by pimps. (Council on Prostitution Alternatives, Portland, 1994)
