In context of the 2010-2012 European Committee of Senior Labor Inspectors (SLIC) Campaign on psychosocial risks, Austria amended its Occupational Health and Safety Act in 2013 forcing all companies to evaluate and reduce psychosocial stressors. To comply with this law more than 300 companies evaluated the psychosocial risks with the Module2 of Psychosocial Stressors (PBM2). 41 of these companies with 21.216 employees already evaluated the effects of their risk reducing measures. Data of total revenue, number of employees and the PBM2 before (t0) and after intervention (t1) were available for 30 companies with19.403 employees at t0. All 30 companies were able to improve their working conditions and reduce work related distress.
