IFALPA is strong enough to make the rules isn't it?
Why not asking as a Worldwide regulation for the airlines to make a full type rating for new joiners eventhough they are allready type rated at airline own expenses with no opportunity to pay them on a lower scale.
That would mean a type rating is only valid for the Airline you are working for.
This would be good also for Airlines as pilots would not leave so easily and only for better salary and T&Cs.
Only the best airlines would attract the best people and this would be also as good for new joiners (no type to pay for) than for experienced pilots (priority because of shorter training).
Just a dream...
