This study explores the influence of guanxi with supervisors on subordinates' thriving at work. Drawing on the socially embedded model of thriving, we propose supervisor-subordinate guanxi as an important interpersonal relationship that generates three resourcesfit, leader-member exchange and work meaningfulnessfor subordinates in the workplace. Use of these resources, in turn, contributes to individuals' positive experience of thriving. The ensuing multiple mediation model is tested on a sample of 221 employees in China. The results extend Spreitzer's model by supporting the theoretical framework and related hypotheses revealing the underlying mechanisms linking guanxi and thriving. Important practical implications are drawn regarding the relationship between leadership, employees' work resources and thriving at work.
