The Eurostar link with Britain and Thalys connections with Belgium, the Netherlands and Germany were also still experiencing cancellations. Services remained severely disrupted on slower French regional and inter-city lines.
But for Paris-region commuters who have been hard hit by the strikes since Dec. 5, the return to work from Christmas holidays brought glimmers of cheer. Just two Metro lines remained completely closed, compared to five that were closed on Friday. There were also improvements on other lines, although not a return to normal, as strikers stayed out for a 26th day.
The disruptions and shutdowns have outlasted a 1995 transport workers strike, testing the will of President Emmanuel Macron to push through with plans to raise the eligibility age for a full pension from 62 to 64. Macron argues the retirement overhaul would make the pension system fairer and keep it out of debt.
Macron's interior minister, Christophe Castaner, insisted Monday that the French public wants the government to press ahead with pension reform. Macron himself is expected to address the issue in a televised end-of-year address on Tuesday.
