This paper presents an overview of research about support-to-work in relation to psychiatric and intellectual disabilities. The overview shows that support-to-work services are multifaceted, and that work can be seen as a tool for individual rehabilitation or as a set of goals to achieve. Providers are presented with specific components, which are characterised by systematic, targeted, and individualized interventions. The overview illustrate a need of long-term engagement and cooperation of and between welfare services and agents within the labour market to dissolving the Gordian knot that transition from welfare interventions to employment seems to be.
