The National Union of Mineworkers (NUM) on Wednesday vowed to fight planned job cuts at ferrochrome smelter Samancor, which could affect 2 400 employees even after a more than 50% electricity price reduction meant to avert job losses. State-owned power utility Eskom on February 27 announced the price cut for Samancor and Glencore’s joint venture with Merafe Resources after the distressed firms agreed last December to shelve planned job cuts while negotiating with Eskom.
