15. Rio Tinto
Though not a household name in the U.S., Rio Tinto is one of the world’s largest mining companies and one of the most notorious corporations for human rights violations and other crimes. From its founding, Rio Tinto has exploited and mistreated its workers. During the Spanish civil war, for example, Rio Tinto applauded then Dictator Francisco Franco’s forces for assassinating their more “radical” (i.e. unionized) workers.
