Codelco strikes labour deal with supervisors at Salvador mine

State miner Codelco, the world's top copper producer, said on Wednesday that it had agreed on a new labour contract with the union of supervisors at its small Salvador mine in northern Chile. The union and company had entered into a government mediated negotiation earlier this month after supervisors rejected the company's previous offer and alleged that Codelco was putting undue pressure on its workers to accept the deal.
