FERNANDES, Rita de Cássia Pereira; ASSUNCAO, Ada Ávila and CARVALHO, Fernando Martins. Changes in the forms of industrial production and their effects on workers' health. Ciênc. saúde coletiva [online]. 2010, vol.15, suppl.1, pp.1563-1574. ISSN 1413-8123. http://dx.doi.org/10.1590/S1413-81232010000700068.
This study aimed to identify determinants of health in workers of plastic industries. Production organization, machinery from maintenance and productive areas, and workers' characteristics of 14 plastic industries from Greater Salvador, Bahia State, Brazil, were described. Data were collected about development policy of each company; marketing, operational procedures; production and quality requirements, and formal rules of work organization. High strain management techniques for production time reduction have been implemented. The increase of work rhythm, reduction of break time, and a situation of high cognitive demand impose to workers anomalous body positioning for performing tasks that imply repetitive movements. Physical and psychosocial demands (repetitive work, lower control of the worker on his own tasks, time pressure and job dissatisfaction) compose a complex of conditions adverse to workers' health. Changes in production management, personnel and business impose new strains into the development of task by the workers and bringing in new risk factors to workers' health.
