PARIS - French President Emmanuel Macron will get a taste of public resistance to his second-term reform agenda this week during the first nationwide strike called since his re-election in April. The 44-year-old head of state has pledged to push ahead with raising the retirement age having backed away from the explosive issue during his first five years in power. But having lost his parliamentary majority in June, the pro-business centrist faces severe difficulties passing legislation, while galloping inflation is souring the national mood. Despite warnings from allies about the risk of failure, Macron has tasked his government with hiking the retirement age to 64 or 65 from 62 currently, with changes to start taking effect next year.
