Workers back as IOC visits Brazil Olympic stadium

But on the second day of its three-day visit, the IOC coordination commission for the 2016 Games was met by news that the venue of the diving competition may be switched to a different location after a request by the international swimming federation, and the company claiming ownership of the land where the Olympic golf course will be built said it will officially notify the IOC about an ongoing legal dispute.

Work had been halted at Maracana on Monday as employees demanded better wages and benefits, but they returned to the construction site after Rio's governor got involved in the negotiation and said a better offer was going to be made.

The union representing the workers said a full-scale strike was still possible depending on the new offer, but work was under way as the IOC's coordination commission stopped by the iconic soccer stadium, which is being refurbished for the 2014 World Cup and the Rio Games.

"Everything was normal when the IOC visited," said Nilson Duarte, the president of the union representing the workers. "A decision on a strike will be made by the end of the week, but it appears that there will be an agreement that will fulfill the workers' demands."
