The role of job security in understanding the relationship between employees' perceptions of temporary workers and employees' performance.

On the basis of psychological contract and social cognition theories, the authors explored the role of full-time employees' perceived job security in explaining their reactions to the use of temporary workers by using a sample of 149 full-time employees who worked with temporaries. As hypothesized, employees' perceived job security negatively related to their perceptions that temporaries pose a threat to their jobs, but it did not relate to their perceptions that temporaries are beneficial. Furthermore, employees' job security moderated the relationships between benefit and threat perceptions and supervisor ratings of job performance.

An examination of the mediating role of psychological empowerment on the relations between the job, interpersonal relationships, and work outcomes.

A field investigation of 337 employees and their immediate superiors tested the mediating role of empowerment in relations between job characteristics, leader-member exchange (LMX), team-member exchange (TMX), and work outcomes. The meaning and competence dimensions of empowerment mediated the relation between job characteristics and work satisfaction. The meaning dimension also mediated the relation between job characteristics and organizational commitment.
