A North Korean labourer has filed a landmark criminal complaint against a Dutch shipbuilding company that allegedly profited from the abuse of workers in its supply chain in Poland and was aware of the “slave-like conditions”, lawyers said on Thursday. A law firm representing the worker – who has not been named for his safety – has asked the Netherlands’ public prosecutor to file a case against a shipbuilder it says knowingly benefited by buying items that were cheaper due to the use of forced labour.
