The increasing prevalence of digitalization, competitive markets, quick environmental changes, and the imperative of organizational sustainability have necessitated business organizations to adopt innovative practices. Hence, all organizations must foster a culture of innovative work behavior among their employees to ensure the organization's ongoing survival and advancement. Nonetheless, comprehensive studies that methodically scrutinize the different factors affecting IWB within a unified theoretical model are insufficient. This research is a literature review to find and analyze factors that influence innovative work behavior. The findings of the literature review or existing research indicate that psychological empowerment, employee engagement, self-efficacy, knowledge sharing, perceived organizational support, climate for innovation, HRM practices, and transformational leadership have consistently demonstrated strong associations with employee IWB in various studies. This study additionally proposes a novel conceptual framework that examines the interplay between psychological empowerment, employee engagement, self-efficacy, knowledge sharing, perceived organizational support, climate for innovation, HRM practices and transformational leadership, with a specific focus on their impact on IWB. This framework holds potential for future investigations conducted by other scholars.
