São Paulo, May 1978. Three slates compete for the leadership of the Metalworkers' Union of São Paulo, the largest in Latin America, with 300,000 associate workers, and presided over by a platoon since the military coup of 1964. In the midst of the Union electoral campaign, the first workers' strikes that would change the country began. Braços Cruzados, Máquinas Paradas reveals, in an engaging narrative, the Brazilian trade union structure of fascist inspiration.
