Argentinian rail workers joined health workers, dockers and others in a 24-hour strike on Thursday 28 July, demanding higher pay.
Rail union reps said that after the failure of negotiations for over 100 days they decided to strike. They also warned that if there is no agreement in a week, they will escalate the action to 36 hours, with a 48 hour strike the following week.
The capital Buenos Aires came to a standstill, with buses also disrupted. Only the tube system carried on running.
