In June 2025, human rights defender Silvio Mendoza, member of the labour union Sintracarbón received threats. Silvio is an active leader of the union and involved in proposals for a more just worker-led energy transition. The threats began after Sintracarbón filed a request with the Labour Ministry calling for the suspension of the collective dismissal of some 300 employees at Prodeco and Carbones de La Jagua (CDJ), subsidiaries of Glencore. This attack is part of broader pattern of intimidation against union leaders in Colombia.
