Just two days before the opening game of the World Cup kicks off in Sao Paulo, Brazil, the nation's metro union decided to suspend its weeklong strike and continue negotiations Wednesday.

The union on Monday night decided to halt the subway worker's strike, which has caused heavy traffic jams in Brazil's largest city, because of pressure from residents as well abuse from city's police force, Al Jazeera America reported.

The Washington Post and BBC have also reported that the union's decision came after the city's police force used tear gas on the strikers Monday amid stalled negations between government officials and union representatives.

"This is the way they negotiate, with tear gas and repression," Alexandre Roland, a union leader, told The Associated Press.

According to The Wall Street Journal, four million people use Sao Paulo's Metro every day and the Brazilian government said that it expects 24,000 people will use it to get to Thursday's World Cup match between Brazil and Croatia.

According to The Independent, one traffic jam reached 106 miles long by 9:30 a.m. on Monday. During the conflict between the riot police and the strikers, officers reportedly threatened the use of guns with rubber bullets.

Chaos ensued as hundreds of protestors took to the streets to smash windows and set aflame overturned buses.

The subway workers issued a strike last Thursday demanding a 35 percent wage hike but following a labor judge's ruling that the strike was illegal, the union lowered its demand to 12 percent, The Post reported.

However, the government said it wouldn't increase the workers' wages to anything more than 8.7 percent, Al Jazeera reported.

A Brazilian court Sunday ruled that the subway workers' union would have to pay $222,000 a day if it continued to strike. Initially the union was forced to pay $45,000 a day for the first four days.

The ruling did not deter the union's decision to continue striking the rest of Sunday and Monday as it voted in favor of trekking along.

The five-line subway system has only partially been running but the trains to the Corinthians Arena have not been arriving. On the streets, traffic moved slowly as cars and trucks were jammed in the gridlock, according to Al Jazeera.
