Abstract
The purpose of this paper is to employ Social Exchange Theory to examine the relationship between organizational trust and work engagement and the role of perceived stress as a moderator in Palestinian ministries. For this purpose, the study utilizes a sample of 178 respondents of executive-level employees in which primary data collection is conducted using survey instrument and PLS-SEM for data analysis. The study proposes that perceived stress moderates the impact of organizational trust on vigor, dedication and absorption, and that perceived stress plays an important role in moderating the relationship between organizational trust and employees' work engagement. The study concludes that implementation of organizational trust is important in Palestinian ministries to support employees’ engagement and to create positive outcome in the workplace.
