Our day schools, even the “rich” ones, already underpay our teachers, and have administrations that while bloated compared to what yeshivos had “in the old country” in the “good old days” (when most people were happy to have two almost square meals on most days, if they were lucky), they are actually unbloated compared to the public schools. Just think for a minute, if you were a goyish bank loaning money at interest (and expecting to be repaid), and someone known to you as a yeshiva rebbe walked in the door, would you jump to greet him or would you look the other way and hope he wasn’t there to ask for a loan.
It might be possible to put the teachers on unemployment insurance, which is being supplemented, but that’s it.
