Industrial action by public sector workers across France today has interrupted most train and Metro services and affected flight schedules.
Unions have called for a massive street demonstration through Paris at midday to protest against the government's plans to reform the 35-hour work week and undermine state health and pension provision.
Around Paris, up to 80 per cent of suburban lines were suspended, and 75 per cent of Metro services cut - with some lines not running at all. Across France, 55 cities suffered various degrees of disruption, with the city of Nice losing its entire bus service.
Air traffic control staff at major airports are involved in the action, and air travellers were advised to check with airlines before venturing to Orly Airport, where up to 75 per cent of flights could be cancelled.
Ryanair has said that flight information is available on their website but that passengers must check in on time.
The unions' action coincided with a visit by the International Olympic Committee to assess the Paris bid for the 2012 Summer Olympics.
But trade unions have pledged support for the bid and are working with the Paris police to minimise disruption for the bid team.
