Workers at Chile's Escondida copper mine threaten to strike over security concerns. They allege that the mining company has not responded to complaints made about possible security risks.
The company's anti-union practices and labor law violations are also criticized by the workers, who complain about the constant violation of their rights.
The private Escondida copper mine, located in the Antofagasta region of northern Chile, is the world's largest copper mine. With Anglo-Australian BHP (57.5%), Rio Tinto (30%) and Japanese Jeco (12.5%) as owners, it is responsible for the production of some 1.1 million tons of copper per year.
