Agri Processors is a wholesaler of kosher meats. Its workers recently voted to join the United Food and Commercial Workers. Agri Processors claimed that the election was invalid because most of the workers are undocumented aliens, and are therefore not legally employees. Agri Processors also claimed that it did not know that the workers were illegal and fired them shortly after the union election. (If you believe that one I want to talk to you about a bridge in Brooklyn I am looking to sell).
Fortunately the DC Circuit called the company on the crap and ordered the company to negotiate with the union. However, the company has announced its intent to appeal the decision to the Supreme Court.
