Many European companies that publicly embrace workers' rights under global labor standards nevertheless undermine workers' rights in their US operations, Human Rights Watch said in a report issued today...Companies cited include Germany-based Deutsche Telekom's T-Mobile USA and Deutsche Post's DHL, UK-based Tesco's Fresh & Easy Neighborhood Markets and G4S Wackenhut security, France-based Sodexo food services and Saint-Gobain industrial equipment, Norway-based Kongsberg Automotive, and the Dutch firm Gamma Holding. "The behavior of these companies casts serious doubt on the value of voluntary commitments to human rights," said Arvind Ganesan, director of the Business and Human Rights Program at Human Rights Watch.
