During the congress celebrated in Zaragoza three months before the beginning of the Spanish Revolution, he was in favor of the most radical, collaborating sectors of the Federación Anarquista Ibérica (FAI). Mera led a strike of construction workers, electricians, and elevator operators in Madrid in June 1936. As a result, he was imprisoned in early July.
