If the EASA recommendation is causing so much grief where you work then is it worth trying to get your management in your own company to read again what EASA actually wrote, perform their own risk assessment and then implement " other equivalent mitigating measures"....or would that cost them too much?
We get told that one Big Airline never introduced that measure, no idea if its true. But over here in germany it was impossible not to implement it, damn the risk assessment which turned out to be not in favor of that measure at all. Simply a bow to public pressure and be done with it.
Due to the very public nature of how that recommendation came to be, it was discussed at length in every newspaper, it is now very easy to get into a flight deck. Especially in a company like mine where several hundred, if not a thousand or more, temporary workers are "bought" from an agency every summer, fast track trained in four weeks and then legally enter the flight deck with just a very superficial "background" check and no psychological evaluation at all.
No need to train a sleeper through flight school, pass rigorous assessment tests and then, after years of training finally be on the flightdeck, every terrorist who wants can be there in just four weeks.
