In Chile, workers at one of the world’s biggest copper mines have voted to go on an indefinite strike beginning next week. The strike at the state-owned copper mine comes just weeks ahead of Chile’s January 17 presidential election run-off. More mining strikes are expected if the center-right candidate Sebastian Pinera wins. He has called for the partial privatization of the state-owned miner, Codelco, the largest copper-producing company in the world.
