Helpful. Like I said, they have leverage, but are too menchlech to use is.
I’m related to school administrators. I know how hard they try NOT to use the child as leverage, but when they must, they go to their Rav and ask for permission to do so. More often than not the Rav contacts the families Rav (whenever possible and if not, the family directly) apprises him (or them) of the situation and more often than not, some tuition is forthcoming from the parents. Sometimes the Rav will tell them that they cant use the child as leverage based on his understanding of the situation. the bottom line is, the schools DO have leverage, but unless pushed hard against the wall, will not use it. They are mechanchim, not mafioso.
