Prostitution is a taboo fringe area of society, about which there is hardly any well-founded information and scientific knowledge. Women who work in prostitution have to struggle with social prejudices, social discrimination and legal disadvantages and therefore need specific counseling and low-threshold services. Social work has a long tradition of helping this target group on a case-by-case basis and advocates for the rights and dignity of women. From the perspective of professional social work, this volume provides an overview of the complexity of the field of prostitution and presents theoretical and methodological approaches.
