This was an era of full employment. Indeed, the maintenance of full employment was the cardinal social objective of every British government in these years. The determination to avoid a return to the horrors of the thirties, when men and machines decayed in idleness, thus trumped any consideration of growth, productivity or efficiency. Trade unions—and especially their local representatives, the factory shop stewards—were more powerful than ever before or since. Strikes—a symptom of labour militancy and incompetent management alike—were endemic to post-war British industrial life.
