The relations between the good soldier syndrome and work satisfaction, personality and socio-demographic variables were investigated in two correlational independent studies, conducted in Romania on contract-based employees from the army and employees from public and private organizations, respectively. The results show that people satisfied with their work tend to frequently adopt organizational citizenship behaviours. These behaviours are associated with the self-efficacy, the internality, and length in service within the organization. In public organizations, the availability to contributing with extra-role behaviours in the work place is more intensive than in the private ones. People having higher education levels get more involved in volunteer behaviours.
