In England, policy developments in the field of mental health are stimulating interest in employment for mental health service users as a means of mental health promotion. To date, research that might assist in increasing employment rates amongst this group has focused largely on the question of which service users are most likely to benefit from vocational interventions and, more recently, on models of vocational support. Less is known about how employers can assist people in their transition or return to work. In this article we draw on the accounts of 17 employment project clients to identify workplace factors that were associated with job retention. Specific adjustments such as flexibility about working hours, work schedules and job tasks emerged as crucial in enabling clients to deal with the effects of medication, and to regain stamina and confidence. Over and above these, however, 'natural supports' of a kind from which any employee would arguably benefit were equally important. In this respect the main themes revolved around training and support to learn the job, supportive interpersonal relationships at work, workplace culture, and approaches to staff management. These themes might equally provide a productive focus for workplace health promotion more generally, using organization development approaches.
