For female street sex workers in Britain, selling sex means managing risks. Violence from male clients, harassment from community protesters and criminalisation through overpolicing are daily hazards on the street. Using qualitative data and extensive field observations of the street market in Birmingham, UK, it is argued in this paper that street sex workers do not passively accept these risks but, instead, manage occupational hazards by manipulating, separating, controlling and resisting urban spaces. Women actively use space to inform their collective and individual working practices to minimise harm and maximise profits. However, the findings conclude that sites of street prostitution are made increasingly dangerous for women through punitive policing policies, conservative heterosexual discourses and a lack of realistic prostitution policy that addresses the central issues relating to commercial sex.
