French workers angry about austerity measures proposed by the former prime minister François Bayrou, whose government collapsed on Monday, are planning to strike on Wednesday, a move they hope will bring the country to a near standstill.

Despite Mr. Bayrou failing a confidence vote, protesters still plan to strike, describing their frustrations as being with President Emmanuel Macron as well.

“The fall of the government is good, but it’s insufficient,” Sud-Rail, a major trade union, said in a post on X on Monday. The union, the third largest rail union in France, whose members mostly work for the national railway company Société Nationale des Chemins de fer Français, urged its members and the public to strike.

Individuals and unions across sectors, including rail and air, say their members will participate. The two-day strike is expected to affect domestic and international travel around Paris and across the country.

The planned strike, which dovetails with a London Underground strike, presents transportation challenges for visitors. Here’s what travelers need to know.

Who is striking and why?

Earlier in the summer, Mr. Bayrou announced his intention to slash France’s 43 billion euro (about $50.46 billion) deficit by cutting two public holidays, freezing pensions and welfare payments and implementing other austerity measures. The plan was met with anger from those who feel that the measures would unfairly hurt middle and lower-class workers.
