In conjunction with the dismantling of psychiatric hospitals, social workers have been commissioned to help service users in their daily living in their homes and in the community. The consequences of these changes for experience-based knowledge and practices in their contexts remain relatively unknown. In this study, eighteen service users and the social workers they described as helpful for them were interviewed. The interviews were recorded, transcribed, and analyzed using Thematic Analysis. The following themes emerged: “Here, there and everywhere”, “Doing, being, becoming”, “Talking” and “Order, planning and improvisation” concerning the contradictions service users and professionals mentioned about their practices and the conditions imposed by managerial methods connected to New Public Management. Finally, “Spontaneous planned complexity” was chosen as our overarching theme to characterize the new knowledge and practices which have been developed. The displacement of the place for the encounter and the introduction of non-medicalized professions have allowed community-based practices and thus the co-creation and emergence of new knowledge about the service users as persons and the professionals as qualified professionals. The challenge remains for managers to have trust in their colleagues and not impose rigid rules, schematized methods, and repeated controls.
