“…They also provide learning opportunities and a supportive environment for selfdevelopment, including assigning certain projects based on their followers' interests (Whittington et al, 2017). Several studies proved its theoretical and empirical impact on performance (Lai et al, 2020;Pradhan & Pradhan, 2016), Organizational Citizenship Behaviour (Buil et al, 2019;Istiqomah & Riani, 2021;Khalili, 2017;Lee et al, 2018), creativity (Istiqomah et al, 2020;Shafi et al, 2020), innovative behavior (Pradhan & Jena, 2019;Rafique et al, 2022), etc. However, there is little evidence related to the effectiveness of transformational leadership on voice behavior (Hu et al, 2015;Wang et al, 2019) A transformational leader changes the followers' values, promotes self-confidence and respect, communicates clear mission statements, and gives individual consideration to these people, as well as integrates their goals in line with the organization's vision, thereby ensuring they behave beyond expectations (Avolio & Bass, 1995).…”
