I truly believe that the reason we all do CRM is for the benefit of the companies we work for.
Because of vicarious liability, the company can say - we qualified the crews in all the latest aspects of CRM and therefore discharged our responsibilities.
In fairness, they can't do any more. Sad fact is, humans are annoyingly human and thus we can all talk the talk, but not walk the walk if it doesn't suit us.
So, I truly have sympathy for the bosses, they can't win for losing. The only real option is 'spies in the cab' cameras and I don't want to even THINK about that route.
Fly safe guys.
