I left CX about 4 years ago and have flown UK charter and am now at BA for the very reasons highlighted previously in between the bickering.
I found CX training to be variable at best, confrontational at worst. I achieved the required standard in each and every sim, without negative feedback, by now I would have likely achieved command.
I find it staggering that individuals such as ACMS rant defensively about the indefensible, the CX training department requires the clean broom treatment, it also requires a reality check because without it, there may not be enough junior ranks left to operate an already stretched operating schedule.
Leaving CX opened my eyes to a training environment that actively encourages learning, an environment that is transparent, an environment that recognizes that we are all individuals with strengths an weaknesses.
Reading this thread makes me glad of where I am.
