Q: Is a Noahide allowed to work on Shabbat?
Q: I work in a factory in Uzhgorod, and they are asking me to work Saturday instead of the next day, Sunday. Is a Noahide allowed to work on Shabbat?
A: Yes, he is allowed, unless when he declared to a Beit Din that he accepts the Noahide laws he also took on a specific obligation to observe the laws of Shabbat. But this is very rare (see Be'er Halacha, in Orach Chaim 304).
