SAO PAULO (AP) A labor court slapped fines on the subway workers union Sunday for a strike that has closed many stations and clogged the avenues of Brazil's largest city just days before it hosts the World Cup opening match.
Angered by the ruling, union representatives said the strike would continue Monday, and its leader warned that the strikers would try to shut down the subway line serving the stadium hosting the tournament's first game Thursday.
Union officials also said other groups promised to join strikers early Monday for a big demonstration at a metro station.
''The government is declaring a war against its workers,'' said Alex Fernandes, the union's general secretary. ''They sit down to talk to us or there won't be subway service during the World Cup.''
Subway workers were angry that the eight-judge panel threatened even higher penalties if they didn't return to their jobs. The court fined the union $175,000 for the first four days of the strike and said it would add on $220,000 for each additional day the work stoppage continued.
Authorities have been able to provide limited subway service, but the strike has resulted in traffic chaos clogging key streets and has closed the main subway stations in Sao Paulo. If the walkout continued Thursday, it would be difficult if not impossible for many fans to get to Itaquerao stadium for the opening match featuring Brazil and Croatia. The stadium is about 12 miles (20 kilometers) east of the city center.
Sunday was the fourth day of the strike, and it closed more than 30 subway stops. World Cup visitors arriving in the city have run into more traffic jams than usual in a city already used to heavy congestion.
''There was no minimum care for the population, causing great disturbance, even in terms of public safety,'' said judge Rafael Pugliese, who was on the panel that imposed the fine.
The Regional Labor Court in Sao Paulo also agreed with management's offer of an 8.7 percent wage increase for subway workers.
The strikers are demanding an increase of more than 12 percent, but the Sao Paulo state-owned company that runs the system says that isn't possible because fares haven't gone up the past two years.
Union leader Fernandes said it won't pay the fines and will appeal the judges' ruling.
The court met over the weekend because of concerns about the strike's effect on the World Cup, which Brazil's leaders had hoped would be a chance for Latin America's biggest and richest country to shine on the international stage.
Police officers, teachers and public transportation workers have staged strikes in the weeks leading up to soccer's premier event. These have overshadowed protests over the cost of putting on the World Cup, which had been feared for possible disruptions following last year's huge anti-government demonstrations during the Confederations Cup soccer tournament.
