In recent years, prostitution increasingly has been recast as a form of ‘sex work’, which directs attention to both the work itself and the larger occupational milieu in which it takes place. This article examines several aspects of the work environment, including important variations between different types of workers (on the street and in indoor venues), relations between workers and customers, and what is known about the role of various managers involved in recruitment, socialization, and control over workers. The article highlights areas in which further research will provide a more complete picture of sex work in different kinds of contexts.
