Fast-food workers and supporters organized by the Service Employees International Union (SEIU) protest outside of a McDonald’s Corp. restaurant in Los Angeles, California, U.S., on Thursday, Aug. 29, 2013. Fast-food workers in 50 U.S. cities plan to walk off the job today, ratcheting up pressure on the industry to raise wages and demanding the right to wages of $15 an hour, more than double the federal minimum of $7.25.
