Hey hey hey... Whats up with all these negative ways.
Take a flight from LEMG (Malaga, Spain) to EFHK (Helsinki, Finland). Normally about 4 hours in MD11. Now you go either directly East and through Italian airspace and then up through Swiss and Austrian or Eastern European airspace. Alternatively you could route West over Portugal and England then Dutch and so on. Either way this adds minimum of an hour to the flight.
I have lost count on how many times Paris ATC has been on strike. No symphaty what so ever towards those dorks. Nice cozy Government job and so on.
Old Jaques should do what Ronny the Raygun did in the 80's and fire the whole bunch. I am sure that there are plenty on english speaking pilots unemployed that would be willing to take a position in ATC for the time being. Put it this way, yapping in french in busy airspace would be a goner
