The union of supervisors at state miner Codelco’s Gabriela Mistral mine in northern Chile has rejected the company’s final offer for a new collective labor agreement, raising the specter of a strike in the coming days, the union president told Reuters on Tuesday.
The union said Codelco, the world’s top copper miner, failed to satisfy its demands for a signing bonus, and that the company was attempting to negotiate different terms for each of the division’s unions.
