“But even so the heter is only to the extent absolutely necessary, and no more.”
Joseph,
So once a woman calculates that she’s earned enough to buy beans and rice for the day she should tell her boss she’s going home? That may be acceptable in the public school system where you spend your time but not in the real working world. Quoting general sources that are not applicable to practical, individual situations is just using fake halacha to find fault with other Jews. But I think you know that already.
