Government employees are vital for delivering services to people, particularly within the Labuhan Batu Local Government. There's a strong need for workers who display innovative behavior to foster public trust. Stakeholders must be deeply committed to improving the quality of employees' work. This study aims to understand how innovative work behavior is affected by factors like professional identity, leadership humility, work ethic, strategies for managing human resources, and job satisfaction. Research on how job satisfaction influences innovative work behavior, considering professional identity, leadership humility, work ethic, and human resource strategies, is scarce. The main purpose of this research is to see how job satisfaction can boost innovative work behavior among employees in the Labuhan Batu Local Government. It uses a Structural Equation Modeling (SEM) approach with Partial Least Squares (PLS) to analyze the data. Data was collected through surveys from 372 permanent staff members in Labuhan Batu. Findings show that job satisfaction is crucial, both directly and indirectly, in linking leadership humility, work ethic, and human resources strategies with innovative work behavior. However, professional identity doesn't significantly affect job satisfaction or innovative work behavior. The study's limitation is its narrow focus on government employees. Future studies should broaden the participant pool and include private sector workers to better understand the impact of professional identity on job satisfaction and innovation at work.
