CHICAGO, IL - JULY 31:  Fast food workers and activists demonstrate outside McDonald's downtown flagship restaurant on July 31, 2014 in Chicago, Illinois. According to a recent ruling by the National Labor Relations Board (NLRB) McDonald's USA can be considered a joint employer at its franchised restaurants, a decision that could affect how the restaurant chain is forced to deal with organized labor disputes.  About 90 percent of the company's restaurants are owned by franchisees.  (Photo by Scott Olson/Getty Images)
