From the perspective of social relationships, this study extends the understanding of employee voice by examining voice outcomes, especially a voicer’s influence in their work team. In particular, we explore how two different social relationships, LMX and peer relationship, separately and jointly affect the ‘voice-influence’ relationship. Drawing on social network theory, we propose that higher LMX and central positions in peer networks (i.e., centrality in the friendship network) strengthen the positive impact of voice on individual influence. From a sample of 128 employees from three firms in South Korea, we found that two types of voice (promotive and prohibitive) are positively related with individual influence. This study also found that LMX strengthened the positive effect of promotive voice on a voicer’s influence. Moreover, LMX and peer relationship jointly affect the voice-influence relationship as follows: (1) a voicer with a high LMX-high centrality (in the peer network) is most influential within their team, (2) as for a low LMX-high centrality member, speaking up rather decreases individual influence. These results suggest that voice outcome is not unilateral. Rather, whose voice it is and where a voicer stands may matter more. We discussed the theoretical and practical implications of these findings in employee voice research.

Prior studies regard psychological ownership as a positive thing, but this study suggested two faces of psychological ownership. Specifically, we focused on the psychological process wherein two different routes via disparate mediators led to two seemingly contradictory outcomes: organizational citizenship behavior (OCB) and workplace aggressive behavior (WAB). In addition, we also examined the moderating role of a structural factor (i.e., network position) in the mediation process. Drawing on the social exchange theory, we proposed that psychological ownership would produce both OCB and WAB through organization-based self-esteem and psychological entitlement respectively, and an individual’s network position would moderate the effects of this process. Data from 189 nurses from a general hospital in Korea revealed that psychological ownership was positively related to two ambivalent outcomes, OCB and WAB. Further, a central position in a friendship network among nurses strengthened the positive relationship between psychological ownership and OCB. Overall, this study showed that psychological ownership was like a double-edged sword. We discussed the theoretical and practical implications of this finding.
