Thanks for posting the list. I had not seen it prior to this, though I had never looked.
My Dad was a 37 year pilot at UAL. Even to the day he retired in '99, he would tell a scab FO that if it did not directly relate to the flight, not to open his/her mouth because they had nothing to discuss.
I know plenty of pilots that actually carry that list around.
You do NOT ever want to do anything to be put on it....ever.
