From what I can understand, today's strike serves a different purpose from that of the current work on rule strike.
The reason they're carrying this work on rule action at the moment (a strike with no name as there is nothing official - how bold of them !!! They still get paid for buzzing those very people feeding them) is that they now have to sign in.
YES how can you expect from anyone to sign in at work ! This is slavery at work. And the reason signing in is such a disgrace to their eyes is that they used to surf on a system whereby people were simply called off from work during less dense trafic periods. Which means these people used to stay home but were still counted as active, working staff : getting paid for not working. How about that !!! This is called the "clearance" system, i.e. forget about coming to work today, you're cleared to dabble in all sorts of leisure activities, doing
Now, the fact they have to sign in with their own ID card and not just waiving at the team as before means they have to take this "work method" out of their life style.
Their argument is "if you want to abide by the rules (i.e. signing in) so will we. All standard, no fuss, no search for improved flight tracks or flight levels. Nothing. All by the charts, obviously forgetting that speeding traffic flows is a hard part of their duty.
Now you know why your airline is wasting so much money in France for these drama queens.
