As Albert Schweitzer said, “The three most important ways to lead people are: by example, by example, and by example.” I believe it is best to have a strong ethical leader than to have a written code and ethical training. People want to see their leaders do things the right way; they want be shown how to do things correctly; and when rules are broken, they want to see justice served.
No wants to be told right from wrong from a boss who disregards the rules. No one wants to be judged or criticized by someone who doesn’t follow the rules. Reading the Dos and Don’ts and seeing no consequence for those who break the rules is counter productive.
The best leaders lead by example and teach by doing the right thing.
