The globalisation process has deeply changed the world of work, creating new challenges for productivity and adaptability in an increasingly deregulated labour market. As a consequence, the employment relationship has suffered the effects of new demands for both external and internal flexibility, leading to a new deal in finding alternative ways to interpreting the employment relationship in itself. Some of these organizational changes have also generated conditions that may affect - more or less directly - the quality of working life, producing unhealthy work environments. As a consequence, a poor psychosocial can be considered as an antecedent for a number of negative and risky situations at work.
