Question: It’s forbidden to have non-Jews do work for us on Shabbos, because amira l’nachri shvus (telling or a gentile do a forbidden act on Shabbos on behalf of a Jew, or even having them do it of their own initiative, is forbidden by rabbinic decree). How is it that many shuls have non-Jews doing work for them on Shabbos? Are they doing the wrong thing, or are there things that may be done by non-Jews?
