Strikes disrupted weekend travel around France on Saturday as truckers blocked highways and most trains remained at a standstill because of worker anger at President Emmanuel Macron's policies.

Meanwhile, yellow vest protesters held their weekly demonstrations over economic injustice in Paris and other cities, under the close watch of police. The marchers appear to be emboldened by the biggest national protests in years Thursday that kicked off a mass movement against the government's plan to redesign the national retirement system.

As the strikes entered a third day Saturday, tourists and shoppers faced shuttered subway lines around Paris and near-empty train stations.

Other groups are joining the fray, too.

Truckers striking over a fuel tax hike disrupted traffic on highways from Provence in the southeast to Normandy in the northwest. A similar fuel tax is what unleashed the yellow vest movement a year ago, and this convergence of grievances could pose a major new threat to Macron's presidency.

The travel chaos is not deterring the government so far, though. Prime Minister Edouard Philippe plainly told the French in a nationwide address Friday: “You're going to have to work longer.”

He will present details of the plan next week. The government says it won't raise the official retirement age of 62 but the plan is expected to including financial conditions to encourage people to work longer. Philippe did offer one olive branch, saying the changes would be progressive so that they don't become “brutal.”

Macron says the reform, which will streamline a convoluted system of 42 special pension plans, will make the system more fair and financially sustainable.

Unions, however, see the plan as a t hreat to hard-fought workers' rights, and are digging in for what they hope is a protracted strike. They also plan new nationwide retirement protests Tuesday, despite the tear gas and rioting that marred the edges of the Paris march Thursday.

In a society accustomed to strikes and workers rights, many people have supported the labor action, though that sentiment is likely to fade if the transport shutdown continues through next week.

“I knew it was going to last ... but I did not expect it to be that chaotic," Ley Basaki, who lives in the Paris suburb of Villemomble and struggles to get to and from work in the capital, told The Associated Press on Saturday at the Gare de l'Est train station. “There is absolutely nothing here, nothing, nothing. There is no bus, nothing.”

Many travelers are using technology and social networks to find ways around the strike — working from home, using ride-sharing apps and riding shared bikes or electric scooters.

But some are using technology to support the strike: A group of activist gamers is raising money via a marathon session on game-streaming site Twitch. Their manifesto says: “In the face of powers-that-be who are hardening their line and economic insecurity that is intensifying in all layers of the population," they are trying to "occupy other spaces for mobilization and invent other ways of joining the movement.”
