There is growing evidence for the effectiveness of workplace interventions to reduce stigma and improve mental health and productivity in a cost-effective manner. A recent literature review supports effectiveness of anti-stigma interventions in the workplace, especially in relation to improvements in knowledge and supportive behavior [13]. A second review provides evidence that workplace interventions that focus on prevention and treatment of mental health problems can be cost-effective [14]. Even when screening and treatment costs are borne by the employer, interventions for treatment and prevention are still cost-saving from the perspective of the employer, as well as for society as a whole [15, 16].
