That's upper management though. Down below the grunts will always do their job, and that definitely includes the air maintenance people. Not a pilot sitting in the seat who's ever regretted that his crew chief and mechanics all have intense OCD when it comes to doing their designated role properly.
My father was an Aeroengine Technician in the RCAF for more than 20 years, and he proudly told me that no aircraft he ever worked on ever crashed.
I don't know about standards now, but when he was still in, they sent techs to training courses every year, even if they already were maintaining the plane they were supposed to be 'trained' on. Dad almost retired in anger before the Air Force sent him on his third training course on the C-130 Hercules, and he retired before they ever got a chance to send him a fourth time.
He had no problem learning new aircraft (or on a new version of a plane), but making him take the same course over and over on the same model (C-130E) drove him bonkers.
After that, he went to a local company that won the contract to maintain Hercs for the Air Force and nobody ever asked him again to 'train' on a plan he'd serviced for almost three decades.
