The airline has put measures in place to Minimise disruptions while asking workers to report for duty, spokesman Tlali Tlali said by text message yesterday. He declined to comment when contacted by phone today. The mineworkers union has given South Africa's gold producers, including AngloGold Ashanti Ltd. and Sibanye Gold Ltd., until Aug. 31 to improve on a wage increase offer of 6 percent for lower-level workers, according to NUM's Seshoka. The union, which represents 64 percent of employees at the seven gold companies participating in centralised talks through the Chamber of Mines, was given permission to strike after wage talks with the producers became deadlocked, the Commission for Conciliation, Mediation and Arbitration said on August 22.
