Charlie, do you pasken that a yeshiva can serve treif so they can pay their staff?
I have to agree with DY here. Out of all the choices they have (closing, firing staff, turning off electricity, etc.) not paying workers may be the best one. When the school’s owner has taken all he can out of his home, sold his silver, and just can’t come up with additional funds, one possible avairah (after asking Da’as Torah, of course) may be the best answer in a bad situation.
