FILE - In this July 29, 2013, file photo, demonstrators in support of fast food workers march towards a McDonald's as they demand higher wages and the right to form a union without retaliation in New York's Union Square. Labor leaders are getting more creative _ and some say more desperate _ in trying to boost their sagging numbers. Unions are helping non-union fast food workers around the country hold strikes to protest low wages and poor working conditions. They are organizing home day care workers, university graduate students and even newly legalized marijuana dealers. (AP Photo/John Minchillo)
