Johannesburg - South Africa construction firm Murray & Roberts said on Tuesday a strike by more than 220,000 engineering and steel workers has halted work on parts of two crucial Eskom power stations.

Murray & Roberts, which is helping build steam generators for Eskom's Medupi and Kusile power plants, said no work was taking place at parts of Kusile and only minimal work was being done at Medupi.

“Approximately 1,400 scheduled employees are not at work at Kusile. We have decided to not send in any other employees to the site until we have further clarity,” said Ed Jardim, a spokesman for Murray & Roberts. - Reuters
