Monday’s protests were centred around Ana Rosa station in central Sao Paulo
The protest was called by Sao Paulo metro workers who are striking in support of a 12.2% salary increase.
Brazilian President Dilma Rousseff has said she would not allow violent demonstrations to mar the World Cup.
Sao Paulo metro workers have been on strike since Thursday, creating traffic chaos in one of the world’s most congested cities.
Metro workers are incensed at the money spent on the tournament and are demanding a 12.2% pay rise
On Sunday, union members voted to continue to strike indefinitely despite a court order for them to return to work and a threat of dismissal by the state governor.
On Monday a spokesman for the company that runs the metro said 60 dismissal notices had been sent out to staff alleged to have been involved in strike-related disturbances in recent days.
However, the company could not confirm that these notices had been received or had taken effect.
Our correspondent in Sao Paulo says that police dispersed the protesters but that it was clear there was a great deal of bitterness about the money spent on the tournament.
