The best terms and conditions exist in airlines where unionisation has been established over a long period
That'd be the same airlines currently laying off pilots by the truckload, would it? What's that you say? No layoffs at Ryanair? Ryanair is actually hiring pilots, and without the benefit of union recognition? Surely not, Max Rear-Eat!
just look at the T&Cs at the likes of Air France, Lufthansa and BA
Not a valid comparison, I'm afraid, Max. The first is a vast monopoly wrapped in the condom of the Fifth Republic, the middle an example of what happens when the Luftwaffe goes commercial, and the third a failing legacy carrier constrained by insufficient runways at its home airport and feral, yes FERAL, unions. Oh, and it takes a brave man to mention BA, Max Rear-Eat, without mentioning their eye-watering pension deficit, but clearly that doesn't feature in your commercial calculus, like so much else. So long as Teez and Ceez are to your liking, with no view beyond the horizon of that.
and do not exercise that right are doing themselves and colleagues elsewhere who are not afforded that protection a great disservice.
Bollocks.
