The aim of this study was to describe family social work through analyzing the roles of social workers. Qualitative research was carried out in three big cities of Lithuania: Vilnius, Kaunas and Klaipėda. Semi-structured interviews were conducted with 25 family social workers. A discursive psychology approach was chosen. Family social workers’ interpretative roles repertoires appear among professional, public and organizational discourses. The results showed that family social workers categorise professional roles in relation to different everyday practices that depend on situated language use in the contexts in which they take place.
