Most school's policies are that you not give out information about students and teachers that could be deemed harmful or personal to them (ex. Who's on and IEP, who is under or over achieving, who has been in trouble at the school.) Seeing as you did not mention any names except for the coaches who are not attatched to the school at all you would break none of your schools policies. Therefore, it is obvious that you just don't want anyone to know where you work.
