The document discusses generalist social work practice and the different perspectives and discourses within social work. It argues that social work knowledge is socially constructed through three interacting arenas: 1) the political-social-ideological arena which influences policy, 2) the agency-professional arena which determines how social work is implemented, and 3) the client-worker-agency arena where practice is enacted. An effective social work approach requires being eclectic in using ideas from different theories, while practicing critical thinking and reflexivity.
