Reducing the workday to six hours with a salary increase for all workers would create jobs for more than 3 million unemployed and lift many out of poverty. Subway workers who have been organizing wildcat strikes for salary increases have spearheaded Argentina's movement for a six-hour workday. In 2003, subway workers (in all sectors from ticket office to train drivers) won a six-hour workday. Since this victory, subway workers, other labor conflicts, economists and unemployed workers organizations have formed a movement for a 6-hour workday for all workers, with increased salaries. The campaign also demands the release of political prisoners and the definitive expropriation of all recuperated enterprises.
