Earlier this month, the United States Supreme Court declined to review a ruling from the Court of Appeals for the District of Columbia Circuit holding that unauthorized aliens are "employees" under the National Labor Relations Act (NLRA) and therefore entitled to cast votes in a union election. 

In Agri Processor Co. v. NLRB, the employees elected the United Food and Commercial Workers Union Local 342 as their bargaining agent in 2005 election; however, the employer refused to bargain with the union on the basis that 17 of the 21 employees who cast ballots were not legally authorized to work in the United States, and therefore not "employees" under the NLRA. 

In a 2-1 decision that was affirmed by the D.C. Circuit, the National Labor Relations Board held that the certification of Local 342 was valid because the voters were employees under the NLRA even if they were hired in violation of the Immigration Reform and Control Act.  That decision will stand now that the Supreme Court has passed on its opportunity to review the case.  With the passage of the Employee Free Choice Act appearing all but certain, authorization cards signed by unauthorized alien employees will likely be held valid as well.
