Industries across France – including rail and transportation workers – went on strike Tuesday to push for pay hikes that keep up with rising inflation, ramping up the clash between workers and the government after weeks of walkouts that hobbled oil refineries and sparked gasoline shortages around the country.

Just one in two trains were running Tuesday in the southern region rail network, causing delays during morning rush hour. There were reports of disruptions on high-speed trains in the north, as well as on the Eurostar and the inter-city trains linking France with Spain.

Other workers, including trucking and bus companies, some high school teachers, and public hospital employees, have heeded a call by an oil workers’ union for French industry to push for salary increases and protest government intervention in the refinery strikes. Thousands also took to the streets Sunday to march against rising prices.

Similar protests have erupted around Europe in recent months as people complain about the impact of inflation, causing disruptions like canceled flights and trains. Thousands protested in Prague twice last month partly about high energy prices, airline workers have gone on strike in places like Germany and Sweden for higher pay as inflation rises, and everyone from nurses to rail employees in the United Kingdom have walked off the job to demand their wages keep pace with the rising cost of living.

Strikers have demanded higher wages from the windfall profits of energy companies that have seen high oil and gas prices as Russia’s war in Ukraine aggravates an energy crisis.

Long lines of cars have been seen for weeks across France as drivers waited –sometimes for hours – to fill up. Many gas stations have temporarily closed while awaiting deliveries. About 30% of France’s gas stations are experiencing temporary shortages, with the Paris area and northern France most affected.
