Workers at BHP's Cerro Colorado mine in Chile plan 24-hour walk-off

Workers at BHP Billiton's Cerro Colorado copper mine, in Chile, will strike for 24 hours in the coming weeks to protest recent layoffs and the company's general attitude toward miners, the main union told Reuters on Wednesday. Earlier on Wednesday, workers briefly blocked the access road to the mine for the same reasons, and later met with the mine's manager.
