Tech crew are highly skilled after years of ongoing training. Life long learning and dedication to the profession to stay on top of the game.
Cabin crew are low skilled workers after 6 weeks training, pass eps twice a year. End of story.
Seniority in some form makes some sense for tech crew. 737 system is obviously fairer. Seniority for cc is a crock. Rewarding c c who have done the same limited skill base job for 20 years, encouraging them to hang around for another 10. WTF? I think a lot of tech crew are not thrilled by the idea of younger junior cabin crew being bullied on board by old angry seniors. Bad for safety .
