Protesters, mostly workers, march towards the Presidential Palace in Manila with an effigy of Philippine President Benigno Aquino III to mark May Day Friday, May 1, 2015, a national holiday in the Philippines. Thousands of workers converged near the palace to call for the resignation of Aquino III and to demand higher wages, better working conditions, fair export labor policies and a halt to contractualization.
