"Peruvian workers denounce anti-union practices by Glencore in Antapaccay mine", 26 June 2025

In the midst of a new collective bargaining process initiated in April 2025, the Union of Civil Servant Workers of the Antapaccay Mining Company (SITRAMINA) and the Unified Union of Antapaccay Workers (SUT) have publicly denounced Glencore - the company that owns the Antapaccay mine in Espinar, Cusco - for alleged systematic practices that violate freedom of association...

From CNV Internationaal we express our deep concern at this persistent pattern of anti-union practices, which violate international conventions and constitutional principles that protect labour rights in Peru...

Union leaders of the organisation claim that since its founding in 2013, a year after the mine began operations, the union has been subjected to a sustained pattern of harassment. Among the most serious incidents are reported..."unjustified dismissals of affiliated workers, pressure to forcibly resign from the union, and the systematic denial of basic rights such as collective bargaining and strike action."...

One of the most critical episodes occurred in November 2013, when several workers were dismissed after joining the union. The company offered reinstatement only if they renounced their union membership.... 28 workers left the union, two were dismissed permanently and five refused to accept the anti-union status...

Glencore has extended the benefits of agreements with financial bonuses to workers in exchange for not joining the union, a strategy that undermines union unity and promotes discrimination.
