This study examines the process of technological change at a unionized manufacturing plant. Using both qualitative and survey data from four categories of salaried and hourly employees at a single worksite, it models and tests several hypotheses to determine which of a series of organizational and technological variables best explain employee attitudes toward new technology. The results suggest that these attitudes are most strongly influenced by the position the employees hold in the organizational hierarchy, and by formal advance notification of the planned technology introduction. Organizational and not technological factors emerge as the strongest predictors of attitudes toward newly introduced equipment and systems.
