The impact of changes in work organization on development of Portugese workers' skills was examined. At the macro level, a national study was conducted to identify current and possible future relationships among initial training, continuing training, the labor market, and industrial relations in Portugal. At the micro level, cases studies of three enterprises were conducted to determine the extent to which new forms of work organization require workers to have additional or different skills the acquisition of which presumes new teaching procedures and/or provide new opportunities for apprenticeships and an opportunity to build on previously acquired skills. Two of the enterprises were manufacturers. The first enterprise had recently adopted the just-in-time system of production, and the second was organized along traditional lines (its research/planning units and manufacturing department were separate) but was also adopting a new work organization that may be described as skill generating. The third enterprise, a major Portugese bank, was changing its work organization in response to the technological modernization that has affected both banking equipment and information systems. The study identified the human resource development issues raised by the models of Portugese society's future. (The bibliography lists 35 references.
