Hundreds of thousands are expected to march in demonstrations across France as trade unions call for a nationwide strike expected to extend to hospital workers, air traffic control, the post office, teachers and rail staff.President Emmanuel Macron’s final months in office continue to be marred by domestic crises, as high school students protesting over poor teaching conditions have been joined by workers in weekly protests over the cost of living. Meanwhile, the government is struggling to pass a belt-tightening budget in a divided parliament as public debt approaches 120% of economic output.Ahead of Thursday’s strike action, France’s four main rail unions said that the government’s proposed budget cuts would “worsen poverty, slash social security, freeze state workers’ salaries and dry up investment needed for environmental measures”.Amid the renewed protests centred on living costs, public spending cuts and the troubled education system, the far-right, anti-immigration candidate Marine Le Pen is polling high for the 2027 presidential election to replace Macron next spring.High school students continued to blockade schools over overcrowded classes and dilapidated buildings, saying the government’s proposed measures on capping some class sizes and loaning funds to regional authorities to fix schools were not enough.

University students joined in blockading some faculties. Trade unions from across the political landscape joined in a call for strikes over the rising cost of living, with private schools’ teachers unions also joining strikes alongside state school teachers.French soldiers patrol a street in Paris on the eve of the strikes.

Trade unions said they also expected secondary teachers to take part in Thursday’s strike.
