REUTERS/Stephanie LecocqPARIS, April 6 (Reuters) - Dozens of trade unionists railing against French President Emmanuel Macron's pension overhaul briefly invaded the central Paris building in which U.S.-based investment firm BlackRock has an office, chanting slogans and setting off firecrackers. The union action in the historical Centorial building near Paris' Grand Boulevards area, targetted BlackRock because of its private pension fund activity, protester Françoise Onic, 51, told Reuters. Thomson Reuters has an office in the same building. The government says change is needed to keep the pension system in the black.
