The oil refinery workers in France rejected the government's order to end their strike and go back to work amid an ongoing fuel crisis in the country.
The industrial action to demand pay hikes has paralyzed six out of the seven fuel refineries in France, leading to shortages of petrol and diesel exacerbated by panic-buying from drivers.
Having previously threatened to use emergency powers to order essential workers back to the job on pain of fines or jail time, the government announced Wednesday it was putting them into action.
Workers at a fuel depot at a refinery in northwest France, owned by U.S. giant Esso-ExxonMobil, will be the first to be targeted, an energy ministry official told AFP.
"Faced with the continuation of the strike by some of the personnel at Port-Jerome in Normandy, the government is launching the requisitioning of essential workers at the depot," the official said.
Government spokesperson Olivier Veran later said that TotalEnergies workers at a northern French oil depot in Flandres, near Dunkirk, would be next.
Long queues of motorists desperately seeking fuel again blocked streets in Paris and other major cities.
As of Tuesday evening, 31% of stations across the country lacked at least one grade of fuel. In the greater Paris region, that figure stood at 44%.
Esther Berrebi, a home health aide in the capital, was trying her third station since 7:00 a.m.
"I'm very angry and very worried," she told AFP. "I understand they want higher salaries, but I don't understand how they can halt an entire country."
The hard-left CGT union leading the stoppages said Tuesday that any requisitioning would be "not necessary and illegal," raising the prospect of legal challenges.
It is seeking a 10 pay rise for staff at TotalEnergies, retroactive for all of 2022, and says management has refused to hold talks.
"It would have been easier to requisition our CEO and bring him to the negotiating table," said Germinal Lancelin, the CGT leader for ExxonMobil at the Gravenchon-Port-Jerome refinery.
On Wednesday, TotalEnergies said it would meet all union representatives, having previously insisted it would meet only those who agreed to end the blockades.
"We'll see what management puts on the table, but this is the first step," said Antoine Lopez, 50, enjoying a barbecue with colleagues at a picket outside the Feyzin refinery in eastern France.
CGT's branch inside the company said bosses had agreed to drop its demand for an end to the refinery strike before opening wage talks, but were still insisting fuel deliveries should resume.
"It's up to the strikers to decide, not us, but I'd lay money on them not agreeing" to the condition, CGT representative Thierry Dufresne told reporters.
Until now, the government had been reluctant to inflame the conflict, but in recent days officials have had to acknowledge the growing frustration and economic damage caused by drivers spending hours trying to fill their tanks.
"Petrol is too important for us. It's been a nightmare for a week," Santiago, a delivery driver, told AFP in Paris.
Even if key personnel are ordered back to work, "it will take at least two weeks" to restore fuel supplies, said Gil Villard, a CGT representative for Esso at the Fos-sur-Mer refinery outside Marseille, in the southeast.
At a time of high energy prices and inflation, TotalEnergies' bumper profits have caused anger, leading to calls for a windfall tax.
The standoff could add impetus to a march planned by left-wing political parties on Sunday against the policies of President Emmanuel Macron and the high cost of living.
"I hope this is the spark that begins a general strike," leading Greens party parliamentarian Sandrine Rousseau told Franceinfo radio Wednesday.
The industrial action comes as Macron is preparing to push through a contentious pension overhaul by the end of the winter, despite warnings from some allies about the risk of widespread resistance.
Labor unions and left-wing political parties have vowed to try to block the reform, which would see the pension age raised to 64 or 65 for most people, from 62 currently.
