How did you deal with upset parents whose child complained about you?

As principal, you will never be able to please everyone. There will be times when staff, parents, and students are upset with you because of some decision you had to make. When a parent is upset, it is best to listen to them, explain why you acted the way you did or made the decision you made, and move on. There is no use arguing back and forth, especially if you were just doing your job. If necessary, you can offer a simple apology, and maybe down the road call home with a positive message about the child.
