While the issue of trust is theoretically essential for the effective operation of correctional organizations, few researchers have examined how the different types of trust are related to salient outcomes for staff. In this study, we examined the effects of coworker, supervisor, and management trust on the job involvement, job satisfaction, and organizational commitment of 322 Southern U.S. correctional staff. The types of workplace trust, however, varied in their effects. Specifically, multivariate analysis indicated only management trust had a significant positive effect on job involvement, but both coworker trust and management trust had significant positive effects on job satisfaction, whereas both supervisor trust and management trust had significant positive effects on organizational commitment. The current findings support the overall contention that workplace trust plays an important role in shaping prison staff job involvement, job satisfaction, and organizational commitment. The results underscore the need for improving perceptions of trust in the workplace, particularly management trust.
