This book brings together contributions from a range of social welfare settings, including child welfare, unemployment, mental health and substance abuse treatment, to examine how interprofessional collaboration and service user participation are realised or challenged in multi-agency meetings. It provides empirically grounded analyses of specific aspects of multi-agency work and offers a distinctive conceptual framework for understanding and analysing interaction during meetings in various social welfare settings. Based on audio and video recordings, the authors provide clear examples of actual practices of social welfare professionals and demonstrate how the realisation of collaborative and integrated welfare policy is contingent on effective interactional practices between professionals and service users.
