Since the strike waves of 1978-1980, Brazil's new union movement has grown far beyond its initial base in the heavily concentrated automobile industry in Sao Paulo's ABC industrial belt. Combative union leaders have won control of major unions in a number of different sectors all over Brazil, particularly in metalworking, chemicals, and bank workers unions.

Brazil's unions remain subordinated to the Ministry of Labor, which retains broad powers including the right to declare unions legal or not, oversee their finances, replace recalcitrant union leaders with its own appointees, and judge the legality of labor agreements in its labor courts.
