This addresses debates on masculinity, masculinities, and management. Starting with an outline of what is meant by the term, masculinities, it discusses the conceptual foundations of theoretical and empirical approaches to the topic in terms of psychoanalysis, sex-role theory, and Marxist and feminist critiques. It moves on to discuss how the term has broadened in recent years, before addressing the confusions and critiques of the term. This ranges from poststructuralist, discursive, and queer critiques. It, finally, highlights various applications of this work on masculinities for the analysis of management, managers, and managing.
