This article aims to explain the effect of transformational leadership on championing behavior with work engagement and trust in leadership as mediators. A literature review is conducted to determine the variables that build the conceptual model. The expected findings are a positive relationship between transformational leadership and championing behavior, as well as the mediating role of work engagement and trust in leadership. This study explains whether the presence of championing behavior will make employees want to be invited to change during the period of organizational change. This study provides an alternative conceptual model in the field of human resources, especially employee behavior. Researchers hope that this research can provide an understanding of the importance of championing behavior to employees and organizations when organizational change occurs. This paper is also expected to contribute theoretically, practically, and may be used for future studies.
