摘要

This article presents a costs-benefits analysis of a macroergonomic intervention in a Brazilian footwear company. Comparing results of a pilot line (composed by 100 multiskilled workers organized in teams) with eight traditional lines (still working in a one human being/one task model) the intervention showed to be worth pursuing since achieved gains were higher than intervention costs: there was a reduction in human resource costs (80%reduction in industrial accidents, 100%reduction in work-related musculoskeletal disorders or WMSD, medical consultations and turnover, and a 45.65%reduction in absenteeism) and production improvement (productivity increased in 3%and production waste decrease to less than 1%). The net intervention value of the intervention was around U$ 430,000 with a benefit-to-cost ratio of 7.2. Moreover, employees who worked in the pilot line understood that their quality of work life improved, compensating the anxiety brought up by the radical changes implemented.
