Workers went on strike over late pay at one of the stadiums enduring the longest delays ahead of the World Cup in Brazil, officials said Saturday, according to reports.
According to Fox News, the work stoppage happened in the southern city of Curitiba, where world champion Spain is expected to be based during football's showcase event next year.
Curitiba Mayor Gustavo Fruet said about one-third of the stadium's 1,200 workers took part in the strike that lasted up to three days this week.
He said protesting workers blocked a city avenue for about an hour on Friday.
The deadline for Curitiba's stadium has already been pushed back to mid-February because of construction delays that officials said resulted from belated financing.
The stadium belongs to Brazilian first division club Atletico Paranaense and is undergoing extensive renovation to host matches in next year's World Cup.
