The Congress of South African Trade Unions (Cosatu), the country’s biggest labour federation, said significant progress was made on Wednesday in its talks with government and business over its proposed plan to cut Eskom Holdings’ debt. “There were broad in-principle agreements” said Matthew Parks, Cosatu’s parliamentary coordinator, in an interview. There was a agreement “there needs to be a big bang intervention,” he said, adding that that applied to other areas of the economy as well as Eskom.
