All umps would be safe from critics if they followed the National League's nine rules of deportment
1—Cooperate with the other umpires working with you. Help each other. Don't hesitate to ask for assistance from each other if you are blocked on a play. The main objective is to have all decisions ultimately correct.
2—Keep all personalities out of your work. You must be able to forgive and forget. Every game is a new game.
3—Avoid sarcasm. Don't insist on the last word. If, after an argument, a player is walking away—let him go!
4—Never charge a player, or follow him if he is moving away—and no pointing your finger or violent gestures during an argument.
5—As concerns umpiring, there is a very old adage and a wise one—"Hear only the things you should hear—be deaf to the others."
6—Keep your temper. A decision on an action taken in anger is never sound.
7—Watch your language! For an umpire to act or use, toward a player, coach or manager, language which, if used toward an umpire, would result in the player, coach or manager being disciplined—will not be condoned.
8—If the manager or captain has a legitimate point to argue under the rules, it is your duty to listen to him. An umpire can do this with dignity and no loss of respect. Be understanding—remember, the players are engaged in a heated contest. You are impartial judges and should maintain a calm dignity becoming the authority you have.
9—Review your work after every game. Only by self-examination will you improve.
