PARIS—More than a million people marched through French cities on Thursday to denounce President Emmanuel Macron’s plans to raise the retirement age, with a wave of nationwide strikes halting trains, blocking refineries, and curbing power generation.
Buoyed by their success, the country’s leading trade unions called for a second day of strikes on Jan. 31 in a bid to force Macron and his government to back down on a pension reform plan that would see most people work an extra two years to age 64.
