||This unit is designed to encourage students to consider the role and significance of leadership in various organisational contexts. The unit introduces the major streams of leadership theory and traces the development of our understanding about leadership. The unit explores how these theories allow us to understand leadership in practice and in what ways leadership is linked to different aspects of organisational effectiveness. It then examines the \\\'good, the bad, and the ugly\\\' sides of leadership, e.g. positive forms (transformational, charismatic) and negative forms (narcissistic and Machiavellian). The unit explores leading for diversity and diversity in leadership (e.g. based on gender, culture and ethnicity) and the role of leaders in constituting ethical and socially responsible organisations. The critical role of leaders in effecting organisational change is explored and the leadership of top management teams, and leadership succession is examined. The unit also examines leadership development programs and instruments and students have an opportunity to reflect on factors that might influence their own leadership style.
