Thousands protested in Buenos Aires against a labor reform pushed by Javier Milei as the Senate began debating the bill, following the CGT’s planned mass march at Plaza de Mayo that mobilized unions and social groups.The proposal would restrict strikes, cut severance pay and allow a 12-hour workday, critics said, while Secretary of Labor Julio Cordero defended the changes as necessary to revive hiring and unions accused police of blocking bus convoys to curb turnout.
