“the discussion is about rebbeim who are not getting paid”
What I meant to say is, the rebbeim SHOULD walk and let the hanhallah see how tough it is to replace quality staff. And while it might be (is?) wise to add a new fresh face to the staff mix every now and then, without a solid backbone of proven, seasoned rebbeim, no yeshiva can make it (unless you’re talking about an upstart outfit with 2nd grade and under only).
Of course, this will mean that only the good staffers will either be taken back (or hired elsewhere) but that’s how it works in the corporate world, and sad to say, yeshiva has become a business, so you need to be ready to play hardball.
