In a world characterized by change, stress at work is a major challenge to workers’ health and to the success of their organization. If to this pressure of changing environment is added the pressure from the working environment caused by improper sizing of work, insufficient control over activities, peer conflict or too rigid hierarchical relationships, the picture that causes the emergence and the manifestation of stress at work is complete. Because of the complexity of the phenomenon of stress at work and the fact that the origin of stress factors in the unfolding process is both in the labour process and at the level of each individual worker, prevention strategies and effective management of stress should be grounded both in employee involvement and in the full involvement of management in an attempt if not to solve, to at least reduce the negative consequences of this phenomenon.
