The purpose of Quality of Working Life (QWL) and Occupational Safety and Health (OSH) is welfare, productivity and worker protection in the workplace. For this reason, the aim of this study is to understand the relationship between these two concepts and thus deduce their significance. The study was performed under a qualitative and descriptive approach due to its interpretativeinductive nature and hermeneutic design. This methodology is used to allow the understanding, explaining and interpreting of the theories proposed for QWL and its relationships with occupational health and safety as a decisive factor thereof. A literature search and content analysis was performed. The results of this analysis the evolution of concepts, their interrelationships and three approaches from OSH are presented. QWL has a comprehensive and multidimensional character, so intervention to issues affecting welfare of workers in their work and family environment is complemented by actions of OSH.
