On 26 May 2023, CNV International, SOLIFONDS (a foundation formed by unions and development organisations), the Swiss Trade Union Confederation, and Andaychagua Mining and Metal Workers Union of Volcan Compañía Minera filed a complaint against Glencore International AG to the Swiss NCP. The complaint alleges that Glencore, a Swiss-headquartered commodity trading and mining company, has not conducted adequate due diligence on its shareholding in Volcan Mining Company, a Peruvian mining company it controls, which is violating employees’ rights to negotiate their terms and conditions of employment and to form and join trade unions. Specifically, the Volcan Mining Company refuses to recognise the Andaychagua Union as a fundamental actor in collective bargaining processes, even though the Union is fully registered as a trade union organisation in Peru.

On 20 February 2024, the Swiss NCP published its initial assessment accepting the complaint and offering the parties its good offices.
