One of the big problems in EK it that there is no formal RT training for new joiners and established pilots alike. Alot of our new pilots are joining from parts of the world where bad RT is a day to day norm and the bad habits are not being ironed out in training.
The poor RT disipline is only going to get worse before it gets better, you only have to see where all the new pilots are coming from, and they don't say "MATE".
It's up to us all to improve the standards, Captains when flying with F/O's who display bad RT should be pulled up and corrected, (not sure what the F/O will say to the Captain!), and during training, the training Captains need to jump to poor RT standards.
Just my thoughts on the matter. I'm sure there's alot more that can be done.
Happy flying and controlling.
