This was on the local radio in Santiago today as well.
Busses, trains and airlines flying out of France might be cancelled today. Not sure if this strike is a one day strike or if it will continue, but if you travel in or out of France in the next few days I would engourage you to call and make sure that you are not affected by this strike.
Further national strike today, expected to affect 1/3 of trains and flights. Info on trains from http://www.infolignes.com/
Flights GB-Spain also affected as they fly through French airspace
Law they're protesting about came into effect at the weekend, so this may well be the last major action before horsetrading starts. Local wildcat action may however continue. Would advise anyone travelling to or in France to check status before setting off.
government has indeed now caved in, scrapping the law that was signed only last weekend. Air and train travel seems to now be back to normal, though I notice there are currently delays on the Toulouse-Bayonne line after a train hit a cow.
