Workers at Chile’s State-owned miner Codelco, the world’s largest copper producer, said on Friday that they would take "action" against what they describe as threats to their jobs.
Tensions with between unions and the Chilean company have risen over complaints about coronavirus prevention measures and the pricing of insurance.
The Federation of Copper Workers (FTC), which represents the mining company’s unions, said the company was in "violation of rights that were legitimately won."
