Subway workers demanding higher wages voted to extend a strike in South America’s largest city three days before it hosts the World Cup’s opening match.Employees will continue their protest today, according to a statement published yesterday on the website of the Metroviarios labor union. The first game of the World Cup will take place in Sao Paulo on June 12 when host nation Brazil takes on Croatia. In the past month, professions from teachers to police officers have walked off the job as Brazil prepares to host the most - watched sports event. Protests have coincided with a drop in support for President Dilma Rousseff, who has confronted criticism over World Cup expenditures and delays in related infrastructure projects. Rousseff has been further undermined by above - target inflation and weak economic growth in the runup to October’s presidential election. The subway employees want Rousseff to help restart negotiations with the local government, according to the union statement. A court ruled yesterday against the strike and said fines would be applied. About 60 percent of Brazilians oppose hosting the World Cup because it diverts away from public services, according to a Pew Research survey released June 3. Dissatisfaction with “things in Brazil today” rose to 72 percent, according to the survey which polled 1,003 people from April 10 to April 30 and had a margin of error of plus or minus 3.8 percentage points.Lead Narrows Rousseff’s lead over opposition candidate Aecio Neves narrowed to 17 percentage points in a May 7-8 Datafolha poll from 28 points in February. She was supported by 37 percent in the May poll, which had a two percentage-point margin of error. That wouldn’t be enough for her to win in the Oct. 5 first round, where a candidate must have more votes than all others combined. Brazil’s consumer prices rose 0.46 percent in May from the previous month, above economists’ forecast for a 0.38 percent increase, the national statistics agency said June 6.
