===Chazzan, Bal Koreh, Mashgiach===
# A chazzan, bal koreh, or mashgiach who are only working on [[Shabbat]] can receive wages, but it’s better that it’s mixed with payment for some work done on a weekday. <Ref>
*The Mordechai (Kesubos 189) quotes from Rabbeinu Baruch both the reasons to permit and to prohibit hiring chazanim or baalei keriah for Shabbos. He writes that it should be prohibited because of Schar Shabbos, but maybe it would be permitted because there is no decree of chazal by a mitzvah. The
S"A (306:5) writes that it is prohibited to hire Chazanim to daven on Shabbos, and some say it’s permitted. As a general rule, when the S"A writes a halacha and then writes “some permit it,” we follow the first opinion. So it therefore it seems, in terms of Sachar Shabbos, that there should be no difference whether the work is a Mitzvah or not.The Aruch Hashulchan (306:12) notes a contradiction with the Mechaber here and the Mechaber by Hilchos Rosh Hashana. Over there (585:5) he writes that one may take money to blow shofar, however he will not see a siman bracha from that money. But over here he writes that it is prohibited (see also Sh"t Yabia Omer OC 5:25 who points out this contradiction as well) .The Aruch Hashulchan writes that because it seems that the minhag is to hire chazanim, it’s probably not prohibited. Yalkut Yosef ([[Shabbat]] vol 2, pg 121) writes that the minhag is to be lenient to hire Chazanim just for [[Shabbat]] as long as one doesn’t speak about the amount on [[Shabbat]]. Nonetheless one doesn’t see Bracha from that money and so one should use that money for buying sefarim or the like.
* Rabbi Simcha Bunim Cohen (The Shabbos Home p. 35) concludes that as long the chazzan or baal korei prepare during the week, it would be permissible because of Schar Shabbos B’Havla’ah. Sh”t Tzitz Eliezer 7:28(7), Sh”T Shevet Hakehati 2:103 agree.
* Sh”t Shaarei Ezra allows a Mohel to accept payment as it’s a dvar mitzvah but preferably he should visit the baby before or after [[Shabbat]] so the payment is mixed with permissible payment. </ref>
