Abstract:
This article presents a macroergonomic intervention carried out in a small footwear components company located in the state of Rio Grande do Sul, Brazil. The company's demand was related to the waste of the expensive raw-material (thermoplastic polyurethane or TPU) used to manufacture the components (high heels pegs). According to the managerial staff, the waste was workers responsibility due to the craft characteristic of the process. A participative method was used to evaluate the problems, propose and implement solutions, as well as evaluate their impact on the workers and the Company. Improvements in the work conditions resulted in increase of workers' satisfaction with the work and in 31.5% waste reduction.
