Workers on strike outside an Exxon Mobil oil refinery in Port-Jerome-sur-Seine, France, on Wednesday.
PARIS—A strike by French refinery workers has choked fuel supplies nationwide, deepening the country’s energy crunch as temperatures drop and Europe grapples with a sharp cut in Russian natural-gas supplies.
The CGT, France’s far-left union, decided on Wednesday to continue a strike that has hobbled the country’s refining system.
The union also moved to extend the strike to a refinery in Donges on the Atlantic coast owned by TotalEnergies SA.
The government on Tuesday ordered employees at a fuel depot owned by Esso -SAF ES, a subsidiary of Exxon Mobil Corp., to return to work, invoking rarely-used legal powers to end strikes.
