A study examined the uncertainty levels and types reported by supervisors and employees at three hierarchical levels of an organization: first-line supervisors, full-time employees, and part-time employees. It investigated differences in uncertainty-reduction strategies employed by these three hierarchical groups. The 61 subjects who completed surveys included employees and supervisors of a local restaurant franchise in the midwest which had recently undergone several organizational changes due to the sale of a major portion of its franchise to a national corporation. Results indicated that hierarchical differences did exist in task uncertainty, but not in organizational or relational uncertainty. In addition, the three groups were generally more Action-type than Inaction-type oriented in their selection of reduction strategies. There were no significant differences between groups regarding strategy selection for task uncertainty. However, part-time employees and supervisors differed in their selection of strategies for reducing organizational uncertainty, and full-time employees and supervisors differed in their selection of strategies for reducing relational uncertainty.
