The Effects of Perceived Organizational Support and Transformational Leadership on Employees’ Innovative Work Behavior : The Mediating Role of Work Grit

This study analyzed the effects of perceived organizational support(POS) and transformational leadership(TL) on employees’ innovative work behavior(IWB), with job grit as a mediator. A survey was conducted among 446 Korean employees, and the research model was tested using structural equation modeling(SEM) with JASP and Mplus. The key findings are as follows. First, POS had a significant effect on job grit but did not directly influence IWB. This indicates that POS indirectly affects IWB through job grit. Second, TL showed both direct and indirect positive effects on job grit and IWB. Third, the mediation analysis confirmed that both POS and TL influenced IWB through job grit, and job grit was identified as a psychological resource that links external factors to innovative behavior. Overall, these results provide empirical evidence that POS and TL impact IWB through the mediating role of job grit. From an HRD perspective, job grit can be regarded as an important antecedent indicator for fostering innovation within organizations.
