This book, first published in 1941, is concerned to relate the argument for Trade Unionism to the needs of women who work, whether in their homes or outside them. It is, in part, a historical analysis of the inter-war years, and it also prefigures the changes to women’s working conditions brought about by the two World Wars. War necessitated the mass employment of women, and Trade Union action had greatly improved the position of the woman war-worker of 1941 compared to a quarter century previously. This invaluable book examines that Trade Union action.
