How does this DUmmie know that his brother didn't put in a good word for him? Getting recommended for a position doesn't mean that you will get it, and the superintendent is probably so busy with start of the year stuff that making a part time job for his buddy's sibling is not high on the priority list.
The time to apply for school jobs was really at least six months ago, or at a minimum, before the school year ended. Looking for a school job now is stupid, especially asking for a part time job to be created for you.
