Companies have been looking for Life Quality Programs as a way to keep the working force motivated and compromised with the businesses` goals, and also try to prevent Occupational Diseases (OD) that causes undesired lay offs and delays in productivity. A great deal of corporation managers say that they look for ways of increasing welfare, comfort and safety for the workers in their daily work in those projects. In this dissertation it was studied the Life Quality Program applied in a company engaged in a road concession in Rio de Janeiro - Brazil, specifically within its toll collectors, with focus on Ergonomics and Labor Gym (LG) projects, in order to know the importance of interaction between the professionals responsible for the development of these programs. Through this work, the hypothesis could be confirmed and became evident that only LG based on the Physical Education is not enough to prevent the OD and promoting the health of the workers, thus needing a direct interaction with the ergonomic factors of the work. So, it is clear that the interaction between the professionals who work with those two programs (LG and Ergonomics) is fundamental so that it reaches the human being in all its dimensions and the exchange of technical information between them allows enrich its work, one complementing the data collection, as well as the other professionals performance.
