This project examined attitudes, expectations, and behaviors that make prostitutes successful in learning to establish their autonomy and work safely. Ethnographic studies were conducted of 47 prostitutes in Canada and 60 in New Zealand through semi-structured interviews, focus groups, and open-ended discussions supplemented by researchers' observations and participation in the culture of sex trade work. Women new to the streets and experienced women involved in various genres of sex work were surveyed as to how they came to acquire a working knowledge about safer sex practices and what specific practices resulted from that knowledge. Findings suggested that, in the course of their daily work, most prostitutes learn to deal with issues of intimacy, decision making, communication, negotiation, and assertiveness. Prostitute practices acquired outside of formal educational systems constituted an alternative body of educational knowledge that could efficiently use community resources to inform and teach about issues concerning safer sexual interactions. Staffed by workers who were in or formerly part of the sex industry, the New Zealand Prostitutes' Collective was the first cooperative effort between the government and sex workers to promote safer sex practices in the sex industry. Sex workers wanted to create an organization that would empower them and advance their political and legal cause. (Contains 27 references.) (YLB)
