Of course, even though controllers, we're still human !
As for training conditions, I was trained the ancient way.
Youngsters couldn't survive this anymore.
Edited to add :
As I don't want to scare anyone (because there's no reason to be scared), I confirm that this was "tongue in cheeck" !
The way I was trained was a bit hard, but that was long ago and only few of my instructors were real hard-holes.
Their motto was : "If you don't resist the way I treat you , you will never be able to resist the traffic !".
Maybe they
were right : flow management was not as efficient as it is now.
And I reckon they didn't even know the meaning of "Human Factors" or "Team Ressource Management". OJTI rating didn't exist then.
Training methods have changed now. A lot !
