The National Union of Mineworkers (NUM) on Thursday said it is unhappy with the load-shedding being carried out in South Africa and “very disappointed” with the performance of Eskom under the leadership of chief executive André de Ruyter. “The current management team has taken the country to stage 6 for the first time in the history of this country. This team is perpetually failing to produce sufficient power to avoid load-shedding. Under this leadership, load-shedding is expected to be with us for the next two to three years,” said Khangela Baloyi, NUM Eskom energy sector co-ordinator.
