It is imperative for organizations to adjust to the external environment to maintain their competitiveness. However, such changes may cause employees to experience uncertainty regarding their job security. Furthermore, organizations are now recognizing the significance of employee retention by focusing on attitudinal work outcomes such as job satisfaction (JS) and turnover intention (TI). Utilizing social exchange theory (SET), this study examined the relationship between job insecurity (JI) and attitudinal work outcomes. Additionally, the moderating effect of Guanxi was explored. Data from 336 employees in Taiwan’s service sector were analyzed using hierarchical regression. The findings revealed that JI has a negative effect on JS but a positive effect on TI. Furthermore, CG was found to moderate the relationship between JI and TI. Theoretical contributions and managerial implications were then discussed.
