Whilst I understand that they wish to convey the importance of adhering to saftey/standard operating procedures, to be honest, imho, that approach of threatening instant dismissal does not benefit anyone, and actually reduces safety procedures.
What it does is result in people not reporting safety issues and procedures that could result in benefits for everyone and puts the fear of God into new recruits so much that they may be frightened and actually make mistakes
Yes think you are right and in fact I suspect that in reality if a CC did make such a mistake it would not necesarily mean instant dismisal. The training for my daughter was very much about report every safety issue - example any ice spotted on plane if CC senior wont listen go direct to pilot. Point (I think!) I was making is that a lot of CC work whilst it may appear mundane is actually very important to overall safety.
