Great post and advice I live by. I believe in a #7 rule too.
7) You must correct those who are not living by these standards. Not tommorow or next week but on the spot correction.
If you see someone bitchin about the company, kindly take them aside and remind them whose name is printed on their paycheck.
If someone is not wearing the hat go to your union standards office and report them. If you see it twice, report them to your chief pilot.
If somebody is fat, invite them to the gym with you. If they say no, call it like it is, "Heh, you like Jabba lets go get on the treadmill". Just make sure nobody is around on this one, so it is your word against his/hers.
Take pride in yourself, your company and the public paying your rent!
