The application of effective interpersonal communication and knowledge sharing is essential for enhancing teachers’ innovative work behavior. This study investigates the influence of interpersonal communication and knowledge sharing on teachers’ innovative work behavior. The research was conducted in a public high school with a total of 283 teachers participating. Interpersonal communication and knowledge sharing serve as exogenous variables, while innovative work behavior is treated as the endogenous variable. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results reveal that both interpersonal communication and knowledge sharing significantly contribute to the improvement of innovative work behavior among teachers. Based on the findings, it is concluded that fostering innovative work behavior requires schools to strengthen interpersonal communication by promoting openness, empathy, mutual support, and a culture of knowledge sharing. This includes encouraging an open, responsive, and collaborative mindset, as well as allocating dedicated time for knowledge exchange, which positively influences workplace innovation. Furthermore, the study highlights that effective communication fosters collaborative thinking, psychological safety, and a supportive environment conducive to the generation of new ideas. Likewise, a structured knowledge-sharing system enhances the dissemination of best practices, peer learning, and collective problem-solving. The results also indicate that organizational support plays a moderating role in strengthening the relationship between interpersonal communication, knowledge sharing, and innovative work behavior. These findings offer practical implications for school leaders and policymakers in developing targeted strategies, such as professional development programs, regular knowledge-sharing forums, and inclusive communication platforms. Such initiatives can promote a more innovative teaching culture that meets the evolving demands of education. This study contributes to the field of educational management by emphasizing the importance of social and informational dynamics in fostering innovation within schools.
