This book investigates the pivotal role played by international industrial unions in the geopolitical shifts that catalyzed the Cold War during the 1940s. Denis MacShane, a former trade union official and politician, utilizes his deep understanding of labor movements to analyze how the ideological divide between Western and Soviet-aligned labor organizations mirrored the broader state-level conflicts of the era. He argues that the struggle for control over global labor federations was not merely a secondary concern but a central front in the early Cold War. By examining the collapse of the World Federation of Trade Unions and the subsequent formation of the International Confederation of Free Trade Unions, the author provides a framework for understanding how labor politics shaped the post-war international order.
