Every there are literally thousands of workers, who are not paid for the work they did. Its called wage theft and it cost workers Billions of Dollars a year in lost wages. For Free Lancers, Independent Contractors and Gig workers its even worse. With the exception of New York City, refusing to pay Free Lancers, Independent Contractors and Gig workers is legal. In fact it one of the things Trump bragged about doing, not paying the people doing work on his buildings.
