In order to support the prevention of psycho-social risks, the OSH Framework Directive 89/391/EEC adopted the WHO’s definition of health as ‘‘a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity” (WHO, 1948).
Starting from the Community Strategy 2002–2006, the Euro-pean Union set out a global approach to well-being in the work-place, focusing on changes to the labour market and the new and emerging risks, psycho-social risks, in particular.
