I would say you should ask a shailah when to ask!
But again things have to be permissible. Are you allowed to steal from one to save another? It’s not me, and I didn’t make the rules. Also, I’m NOT a Rav. So I really can’t write an answer. That’s just how it appears to me.
Let’s say, for instance, your case of a school. Are you notifying direct, or posting it here openly? Maybe one is forbidden from causing so much harm to a party involved? What defines ‘does not supervise’? These are real valid questions a Torah Observing Jew would certainly want clarified.
