조직 내 상이한 네트워크가 직무태도에 미치는 차별적 효과

Social networks in organizations can be seen as sources of information in the development of job attitudes such as job satisfaction and organizational commitment. Previous studies on job attitudes have been focused on the interplay of objective job characteristics and individual properties. However, deep understanding of the effects of social relationships still remains limited. Drawing on social information processing (SIP) theory, this study examined the different effects of social networks on individual job attitudes. We proposed that intra-group task advice network would have more significant effect on job satisfaction; extra-group friendship network would be better predictor of organizational commitment. We collected 397 individual-level network data from 11 Korean firms and analyzed different effects of group- and organization-level indegree centrality and ego-density (embeddedness) using UCINET 6 for Windows and hierarchical regression analysis. Major findings are as follows: (1) Centrality and high degree of ego-density in intra-group task advice network, rather than organizational-level relations, are found to have more significant influence on individual job satisfaction. (2) As centrality and ego-density in extra-group friendship network increased, individual organizational commitment were also increased. All in all, this study found different effects of group- and organization-level social relations on different job attitudes. Based on these findings, we discussed theoretical and practical implications of the study and some directions of future research.
