South African power utility, Eskom says if the wage demands being made by unions would be accepted as they stand, it would add an additional 30-percent to the more than 33-billion-rand in employee benefits and wages, which the power utility paid in the year ended March 2020. This as the National Union of Mineworkers and the National Union of Metalworkers of South Africa are demanding a one-year, 15-percent wage increase, while Solidarity wants a 9.5 percent increase, demands Eskom spokesperson Sikonathi Mantshantsha says are clearly unaffordable.
