Agree with you EYZ.
From where I sit in my FO seat, there is definitely no culture of a steep cockpit gradient in EY. I'm part of the team, and generally made to feel so. If thats not the case and I feel that I'm not being included in the loop, then its up to me to do something about it.
re doors, signs, ACARS, and even taxying on PF sectors - well there are just bigger things in life to concern me.
