Workers at Anglo American Platinum, the world's top platinum producer, have been on strike since last Friday in protest to planned job cuts the company says it needs to return its operations to profit. Amplats has said it is losing an average of 3,100 ounces of production a day from the strike. Gold producers and unions agreed to wage hikes of up to 8 percent last month, ending a three-day strike. Those settlements are expected to amount to 1.5 billion rand in extra costs for companies.
