Gadolhadorah

If one is teaching at yeshiva for boys and has not been paid or is paid a below-market salary, there is no chiuv for the rebbeim at that yeshiva to continue working without pay and forego taking another job through which they can feed their own families. That may mean a position in chinuch at another yeshiva or any other position that will provide the requisite compensation. Ifs up to the parents of the talmidim at that first yeshiva to assure that hey pay their tuition so that the teachers are paid on time or if not, to transfer their bochurim to another yeshiva. The obligation on chinuch and limud torah is on the parents; the teachers are not obligated to work without pay.

Daas Yochid:
If the reason the rabbonim and morim in this school are striking has to do with their not being paid or that their salaries are not enough to live on, why would it make a difference if their talmidim are boys or girls?? Teachers are working to support their families and the gender of their students doesn’t change that economicreality.

With few exceptions, a shadchan relies upon her/(his) time to earn a parnassah. They are professionals who should be treated in the same way you would call ahead to reschedule a meeting with your lawyer, doctor, real estate broker, etc. While most will give you a “one-time” dispensation on the theory you forgot the appointment or were unavoidably detained, you should at least apologize for the prior “no-show”. Even if they are doing the shadchanus with no charge, they are still entitled to respect for their time.
