Encouraging employee voice: coworker knowledge sharing, psychological safety, and promotion focus

This study investigates why and when coworker knowledge sharing encourages employee voice behavior by exploring psychological safety as a mediator and promotion focus as a moderator. We tested the hypotheses using 68 dyads (study 1) and 289 dyads (study 2) collected from South Korea. In both studies, we found the positive indirect relationship between coworker knowledge sharing and voice behavior through psychological safety. Moreover, in Study 2, we examined how promotion focus moderates the positive effects of coworker knowledge sharing on voice behavior via psychological safety. The implications and directions for future research are discussed.
