The Moderating Effect of Job Security on the Relation between Role Clarity and Job Performance: A Longitudinal Field Study

In a longitudinal field study of a random sample of employees in an organization undergoing major restructuring and downsizing, we investigated the moderating influence of job security on the effect of role clarity on employee performance. The results support our hypothesis. That is, job performance increased over time under higher levels of role clarity. Moreover, this increase in performance was maximized when both role clarity and job security were high, while deterioration in performance was greatest when role clarity was low and job security was high.
