Parents of students- I was once in the situation where the school was hopelessly behind in paying the Rabbeeim, and the Rebbe called the parents to pay him. I asked a shailoh and was told , I was pottur mdinei odom but possibly chayyiv b’dinei shomaim. I was advised to pay him if I could afford it which I did. I pulled my kids out of that mosad and my children have been matzliach, more than I could have expected. I attrribute there hatzlocho to my not handling the rebbe.
All parents should make sure that their children’s rebbees,moros and teachers are paid b’yahsrus. If parents demand it, it will happen.+
