Vocational rehabilitation offers an exciting and rewarding field of practice to occupational therapists working in the field of psychiatry and mental health as one of the final stages in the rehabilitation process. Cognitive, emotional and motivational difficulties are at the core of most mental illnesses and may affect worker's ability to perform their essential work tasks efficiently and accurately. Various models and theoretical frameworks can be used during the vocational rehabilitation process as applied to clients with mental illness. Workers with mental illness, who are employed at the time of the initial vocational assessment, could return to employment using transitional work programmes (TWPs) where they return to work in a restricted or modified capacity for a specific length of time. Occupational therapists with expertise in vocational rehabilitation are increasingly moving into corporate and industrial work settings as consultants to employers on issues of disability equity and disability management.
