Abstract
The present study exmined the effects of environmental uncertainty (EU) and participation in decision making (PDM) on employee job satisfaction (JB). This study used the Organizational Expecptancy Theory (Sakashita, 1985) and the Schuler's model (Schuler, 1980) as the paradigm for an analysis. Based on these two models, this study proposes a new model. The following four hypotheses were constructed. First of all, the negative relationship between EU and role perception was hypothesized. Secondly it was hypothesized that EU would decrease JB and that role perception would intervene between them. Thirdly, the positive relationship between PDM and role perception was hypothesized. Finally, it was hypothesized that; (1) PDM would have a positive effect on JB regardless of the degree of EU, (2) EU would have a negative effect on JB regardless of the degree of PDM, (3) the greater EU would be, the greater the effect that PDM increases JB would be. Questionnaires were administered to 102 empolyees working in 41 different organizations. Results mostly supported the four hypotheses. And the new model was partially substantiated by the data.
