“…Müller and Turner (2007) indicate that toxic leadership is a structural response to the mismatch between project type and JV Lead Management leadership style (Powl and Skitmore, 2005) and are seen by many researchers as being ineffective (Kellerman, 2004), when viewed with personal traits and organisational factors (Harvey et al, 2007) and appear destructive in terms of performance and personal responses (Harris, Kacmar and Zivnuska, 2007). However, leadership is required to help pursue major stakeholder satisfaction resulting in a project's success (Toor and Ogunlana, 2008).If a project's leadership behaviour changes to a destructive mode, then the major stakeholder's also show such destructive leadership tendencies (Toor and Ofori, 2008;Shaw, Erickson and Harvey, 2011) creating vulnerable work environments (Padilla, Hogan and Kaiser, 2007) raised from such narcissistic and manipulative leadership behaviour (Rosenthal and Pittinsky, 2006). For example, in susceptible work environments, toxic leaders often utilise control, bullying and coercion (Hogan, Hogan and Kaiser, 2003), and abusiveness (Tavanti, 2011) as their main method for ensuring authoritive acceptance (Higgs, 2009)through narcissism (Maccoby, 1999) related to unethical behaviour (Niehus, 2011) and lack of integrity (Blair, Hoffman and Helland, 2008).…”
