Airspace Closed

Since last Friday afternoon to Saturday noon, the Spanish airspace has been closed. The cause, a covert strike by air traffic controllers. I say hidden, because 70% of air traffic controllers have been sick.
The Spanish government has ruled the state of emergency. Thus, the military has taken the airport control tower, forcing air traffic controllers to return to work, because if they disobey, it became a crime, with jail sentences.
The cause of the alleged strike, on the one hand, privatization of the airports in Madrid and Barcelona (also, 49% of privatizing state-owned airport control: AENA). On the other hand, the change in the valuation of the hours worked by air traffic controllers.
Chaos, is what has brought this crisis airport.
