North Korean laborers turn up on construction sites across Europe, sent abroad by their government and stripped of most of their wages before they ever see them. VICE News traces the story back to a 2014 accident at a shipyard in Gdynia, Poland, where a welder died on the job with no supervision and inadequate protective clothing. He turns out to be one of an estimated 50,000 North Koreans working under similar arrangements throughout Europe, in agriculture and construction as well as shipbuilding, generating more than two billion dollars a year for Pyongyang. Reporters obtain internal documents laying out what these workers actually earn before deductions taken by the regime, and try to question both the laborers and the agency placing them, getting only silence and fear in return. Labor inspectors and activists are more willing to talk, describing what one source calls the world's largest illegal job agency, while the companies and officials involved deny any wrongdoing and the arrangement continues.
