Don't make sarcastic remarks about a ball player and in no way make any remarks about your partner in the vicinity of players. If you are involved in an argument with a player of the game or coach don't insist on having the last word - let them go - DO NOT FOLLOW THEM.

Always remember to keep your temper. We are the only people on the field many times that have a cool head. Remember a decision you make in anger is not always a sound one.

Don't ever use language toward a player or coach that you would not let them direct at you. Not only are players and coaches disciplined, but umpires are also open for discipline

One tenet of the Umpires Code of Ethics is: "Co-operate and be professional in your association with your fellow umpires and do nothing to cause embarrassment". If you and a friend are at a game, after a controversial call, you must not be seen dissecting the play. You can't afford to show disapproval either verbally or with body language. Even if the call was the worst you have ever seen, you must remain silent.

Thanks to Geoff Robertson for the post.
