ISCOR said on Friday that a week-long strike at its Grootegeluk coal mine in Northern Province has been called off. The strike, which started last Wednesday, was in response to the dismissal of National Union of Mineworkers chairman at the mine, ML Ngoepe, for serious misconduct. Iscor spokesperson Phaldie Kalam said employees will return to work on Sunday. He added that employees will not be paid for the period of their absence.
