This diploma thesis deals with the relations created between social workers and women, providing paid sexual services, in the area of street work environment. The thesis shows us the process of creation of these relations on the basis of the specific position of its actors, such as the stigmatized sex workers and "the wise" ones in the area of social work. However, these positions are not fixed. Social workers, as well as sex workers transform and redefine them, by using their own ways of understanding to categories such as trust, authority and process of self definition. The relations between the actors are mainly created on the basis of the topic of health that enters this environment through the harm reduction approach. This approach is also responsible for bringing an attention to actual health of sex workers but moreover an attention towards group of these women as such. Nevertheless, in the process of actual field research, were these categories shown as to be part of a larger picture of topic like motherhood and partnership. The last chapter of this thesis discusses the approach towards these topics during the contact with social workers.
