“…Bass (1990), Yukl (1989) and Yukl et al (2002) provide a review of leadership behaviours. However, they fall broadly, with some overlaps, into the following categories: stewardship (Hernandez, 2008), transactional (Hackman et al, 1992), transformational (Hackman et al, 1992; Piccolo and Colquitt, 2006), authoritarian (Kiazad et al, 2010), charismatic (Conger et al, 2000; De Hoogh and Den Hartog, 2009), narcissistic (Chatterjee and Hambrick, 2007; O’Reilly and Chatman, 2020; Rosenthal and Pittinsky, 2006), autocratic (De Hoogh and Den Hartog, 2009) and heroism (Allison et al, 2017).…”
