Supporting the working careers of patients having mental disorders is in the best interest of the individual, the community and the society. In mental disorders, recovery to be able to work is more challenging than in other disease groups. Vocational rehabilitation yields the best results when implemented early enough and in close association with work. Work trial and preparation for work are among the most common means of rehabilitation supporting mental patients' return to work. Collaboration with the workplace is needed when the work and working hours are adapted to the needs of the rehabilitee. Supported employment helps even the severely ill to be able to return to work.
