My 40-year-old mother has been idle at home and unemployed since she divorced my father a year ago. Now someone has introduced my mother to work as a masseur in a bathing city. Is this okay?

As long as your mother knows this craft, you can go. The key prerequisite must be formal. If your mother is old-fashioned, you can't go, because in that place, you will inevitably be teased by men and even get stuck. Your mother has an open mind. As long as she works properly, she won't be able to do what others think. The best way is to find an ordinary job, because she will have to find a husband in the future. Most men don't like that kind of place.
