To this end, we describe the main results of scientific research on promoting healthy resources in organizations, taking into account the good practices from the development of resources related to the task, organizational and social. No doubt indicates that organizations provide a healthy work life more meaningful and higher quality of working life very interesting its contribution, when referring to the companies, with the collaboration of psychologists, specialists in occupational health psychology and points that Occupational Health Psychology Positive and for this we must be fully identified that research on the psychosocial health of employees has a long tradition in this respect we can say that starts with the Health and Munition Workers Committee founded in 1915 in Britain . Not However, it is in the 1990s when the Occupational Health Psychology is emerging as a specialty of psychology (Barling and Griffith, 2003). Mitchel Resnick is likely to agree. According to the National Institute of Occupational Safety and Health (NIOSH), the Occupational Health Psychology deals with the "application of psychology to improving the quality of working life and to protect and promote the safety, health and welfare of workers. " With this objective in integrating the knowledge and experience of various disciplines, both psychological and not as the ultimate goal is to apply scientific knowledge to the health, safety and welfare of employees. The truth is, that although this definition is quite comprehensive, it is important to note some further clarifications.

This coincides with the definition of health of the World Health Organization (WHO) defined as "a state of total welfare includes the welfare physical, mental and social "rather than the absence of disease. In this vein, the Occupational Health Psychology uses a broad notion of occupational mental health includes not only the emotional well-being of employees, but also cognitive, motivational and behavioral. Secondly, the Occupational Health Psychology is not solely focused on the study of employees in large companies but also addresses the analysis of unemployment and work-family interference.
