The book provides a rich kaleidoscope of critical engagements with leadership in all its complexity and ambiguity. The contributors to this collection do not deny the vital role that leadership can play nor the many ways in which it can affect the emotional dynamics of organizations for good and bad. What they do is to shift thinking away from the comforting but misleading simplicities of toxic leaders and inert followers, offering a welcome tonic to the critical study of leadership. The book will appeal to leadership scholars as well as to students and to refl ective practitioners. Yiannis Gabriel, University of Bath, UK. 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.
