ok, maybe their maths is diffrent

, or they just think about single man/woman operations, by the way, wasn't there something over and in Überlingen?
Hope if something happens(but better hope that nothing really serious happens), Russians will be the victims, they gonna find out those managers.
So presently it seems that Spanish Air Traffic Control is managed by arbitrariness and powerhungry markmaking managers.
One, sorry two last questions:
Are you sure Spain is a civilized country in the EU and is Francisco Franco really dead?
If this dispute is going on some while it might be of high interest for the newspapers all over Europe regarding the next summer season, in regard of safety, tourism industry will have an eye on it.
But Espana don't need the tourists
Keep on negotiating, come back to normal procedures and find to make a compromise.
If staffing is too low, then negotiations should be done in this way, with time and head(staff numbers) goals. If those are not achieved a bonus for the current staff will be paid(like a fine).
Well the working hours presently (1750) seems to be slightly above the average in Europe.
If they are trying to get some personnel from other ATC Units I think in the present situation nobody will change. I'd rather get pissed in Austria than in Spain although its a very nice sunny country with very nice people.
Hasta la vista baby!
