Macroergonomic analysis of two different work organizations in a same sector of a luminary manufacturer.

This article presents the analysis of the effect of two different types of work organization (the traditional and a new mechanized, more segmented one) in the packing sector of a luminary manufacturing company in Curitiba, Brazil. A macroergonomic analysis was conducted to evaluate the workers satisfaction with the job; the possible associated postural risk, the level of body pain/discomfort and to compare the two models (traditional and mechanized). The mechanized model showed to involve higher postural risk, to generate more pain and less satisfaction, even in relation to the temperature, illumination, uniform and salary, which are the same for the two groups. Excluding job rotation that was well evaluated and should be adopted for all workers, the new model proved to be worse than the traditional although it also needs improvements.
