In the literature on industrial conflict, the Italy of the 1950s is often described as marked by worker acquiescence and an absence of conflict, ensured by high unemployment and the severe repression of union activism. My research challenges this. While formal, organized collective action subsided, workers continued to show their defiance and opposition to factory authorities by means of diverse acts of individual resistance that have escaped scholarly study. Drawing on anthropological theory, particularly Scott's notion of 'weapons of the weak'the strategies used by subordinate classes when facing heavy repression or lack of resourcesthis article undertakes an innovative analysis of the use of insults, irreverent behaviour, rumours and mockery of foremen and bosses to undermine the authority and legitimacy of factory hierarchies. It casts new light on the protest cultures and practices of Italian workers in the 1950s and improves our understanding of post-1945 industrial conflict.
