This book offers a critique of the field of leadership studies, focusing on the dynamics between post-heroic leadership and the notion of functional and dysfunctional emotions. Situated in the field of critical leadership studies, the chapters of this book set out to challenge the general assumption that emotionality is the antithesis of rationality. The authors expand upon the existing discussions of leadership emotions and reveal how toxicity and dysfunctionality are not merely simple, negatively coercive, or repressive phenomena, but can also have productive and enabling connotations. The book includes comprehensive overviews of traditional leadership thinking and in addition provides readers with critical reflections on concepts such as ignorance, authenticity, functional stupidity and vanity in leadership. As the book presents a series of critical perspectives on how emotions can be theorized in leadership studies, it is suitable for advanced courses in the subject, as well as being a highly interesting monograph for academics in the field.
