French unions stepped up their fight against President Emmanuel Macron’s pension reform plans on Tuesday as most trains came to a halt, fuel deliveries were disrupted and schools shut on the sixth day of nationwide strikes. This is a critical time for the government, which is hoping the reform can be adopted by parliament by the end of March.

To increase pressure on lawmakers not to raise the pension age by two years to 64, unions said there would be rolling strikes this time, which could go on for days, including at oil refineries and railways. “We will continue until the reform is withdrawn,” the head of FO union, Frederic told RTL radio. Garbage collectors and truck drivers joined the strike, in a sign the protests were spreading to more sectors.
