I work for yellow and a few years back they hired a conway and a ups supervisor, not at the same time mind you.....they tried to act tough and slam clipboards and yell.....funny thing happened....they learned real quick that they were in a union barn ...meaning if they yell we can yell if they curse we can curse......actually the stewart did the yelling for us....the difference between union and non union shop is they can say what they have to say without getting in your face and threating your job, I am sure every man on this board will agree that there is a certain amount of room you give an man that is his personal space.......I worked for old dominion in the south a long time ago so I know exactly how they talk to people and how they treat them, just my 2 cents....thanks
