Abstract
Employees' perceptual expectancies as an explanatory framework for the effectiveness of participation in decision making were investigated in a large public utility organization. The results supported the hypothesis that the effectiveness of participation in decision making is mediated by employees' perceptual expectancies of the effort-performance and the performance-outcome relationships (n = 383). The results also suggested that the types of employees' perceptual expectancies may have different mediating effects depending on the criteria selected.
