A strike by metro workers in Sao Paulo, Brazil’s biggest city has been suspended.
But the industrial action could resume on the opening day of FIFA’s 2014 World Cup.
A union spokesperson said the strike could start again on June 12 depending on whether 42 workers who have been fired are re-instated.
The walkout is in support of a 12 percent pay claim which is well above the company’s offer of 8.7 percent.
