On April 28 we saw a massive general strike in Brazil, the first in over twenty years, which we reported on, but before this, in Argentina there were dramatic events during a mass trade union rally where the union leaders were booed and shouted down and had to escape the wrath of the workers, escorted by security guards - “unprecedented” for a trade union rally in Argentina. The reason for the anger was the refusal of the leaders to fix the date for a general strike. In both Brazil and Argentina the working class is on the move. Here we provide a report from our comrades in Argentina.
