Social workers' interventions in support of children and their families have often proved a minefield of sort, filled up with conflicting demands, expectations and tasks. This paper sets the resulting debate in the context of both social policy orientations and social work cultures. It argues that partnerships between families and practitioners have to be understood as the result of a complex set of factors. Data from a qualitative study of social work professional cultures suggest that among practitioners, policy orientations intertwine with different styles of conceiving social work; accordingly, professional cultures play an important part in connecting, or failing to connect, child protection and family support.
