PARIS — A nationwide strike by French public sector workers on Tuesday was causing disruptions in domestic air traffic.

Nine public sector unions called for nationwide industrial action to protest against President Emmanuel Macron’s economic policies which they say would result in deteriorating work conditions.

The unions are angry at plans to tighten rules for sick leave, freeze salaries and decrease the number of public sector employees in the next five years.

Carrier Air France says about 25% of domestic flights would be cancelled due to a walkout by some traffic controllers. The airline expects to run all long-haul flights to and from Paris airports.

Railway traffic was expected to be close to normal.

Jean-Claude Mailly, secretary general of the hard-left FO union, called on Macron to stop “austerity” policies toward public servants during a protest in the city of Lyon.

Tuesday’s action day staged by public workers unions comes after several other street protests in recent weeks against Macron’s labour reforms, which apply to employees of the private sector. Unions fear Macron’s economic policies would weaken France’s hard-won workers protections.

The hard-left CGT union called on new protests and strikes against Macron’s labour reforms on Oct. 19.
