My thought was that they shouldn’t be allowed to do jobs that benefit the outside society at all. They can grow and cook their own food, clean their own living spaces, sew and launder their own clothes etc and maybe hold an outside job as part of a finite period for reintegration but I don’t like the idea of them being allowed to work outside the confines of their incarceration because I worry about a society being able to benefit in any way from incarceration. I think it should always cost way more to lock people up than to let them be free. If you think it’s worth it to keep this person out of society put your money where your mouth is. But yes at the very least they should be paid as much as a normal employee would have to be.
