Some French train drivers, teachers and others are on strike to reject a government reform relaxing the 35-hour workweek and other labor rules.

The strike is not affecting Paris' Charles de Gaulle airport, but 20 percent of flights at Paris' Orly airport have been canceled. The strike also affects public hospitals and state-owned broadcasters.

State railway company SNCF has warned of disruptions to national and regional train traffic. International lines to London and Brussels should not be affected.

Student organizations and employee unions have joined to call for protests across France to reject the Socialist government's bill, which they consider as badly damaging hard-fought worker protections.
