Production Uncertainty as a Contextual Moderator of Employee Reactions to Job Design

A number of authors in the job design field have proposed production uncertainty, the degree to which a qualified incumbent faces unexpected problems in the course of job performance, as a possible moderator of the effectiveness of job design. However, empirical support for this view is limited and has not been explicitly recognized within mainstream job design theory. This study of production operators in a waste water treatment setting provides further empirical support for production uncertainty as a contextual variable influencing job design outcomes, demonstrating that the relationship between job control and affective outcomes (job satisfaction and intrinsic motivation) varies with the level of production uncertainty.
