There are tales of BMI guys getting a very hard time at OPC's & LPC's that is not justified by the normal professional standards,
TBH there are also tales of BA guys, even "long term" ones, and yes even P1's getting a hard time in the sim, and there have even been downgrades from Left to Right, but in my experience when you get to hear
both sides of the story you often find that the trainer(s) had a point.......
I can only talk for the Boeing side of things but in my experience the trainers are pretty objective and the system (the likes of the feedback loop Locked Door refers to) tends to sort out any overly zealous individuals...
