Disentangling the effects of promised and delivered inducements: Relational and transactional contract elements and the mediating role of trust

Abstract

Psychological contracts contain both relational and transactional elements, each of which is associated with unique characteristics. In the present research, the authors drew on these distinct qualities to develop and test hypotheses regarding differential employee reactions to underfulfillment, fulfillment, and overfulfillment of relational and transactional promises. Further, the authors extended their test of the theoretical distinctions between relational and transactional contracts by assessing the relevance of trust as a key underlying mechanism of relational and transactional psychological contract breach effects. Participants in this 3-wave longitudinal study included 342 full-time temporary employees. In support of existing theoretical distinctions, results indicated that employees reacted differently to varying levels of fulfillment of their relational and transactional contracts and that trust is a more central mechanism of relational, as opposed to transactional, psychological contract breach effects. These findings underscore L.S. Lambert, J. R. Edwards, and D. M. Cable's (2003) recent recommendation that the traditional conceptualization and study of psychological contract breach requires expansion. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
