But everything in prison is being done to you against your will. That's kind of the whole point. I don't see why being required to do a moderate amount of work under humane working conditions is so much worse than being required to sit there in a cell at other hours with no ability to leave.

(If the working conditions are not humane, then that's a different story).

They also do usually receive pay, just less than minimum wage. So put a different way - I don't see why the minimum wage within a prison should necessarily be the same as the minimum wage outside of prison.

If the prisoner is attractive to a guard, they might as well be forced to have sex against their will. That's kind of the whole point....? Sorry, what's the whole point? Incarceration does not imply exploitation. Exploitation is an abuse of power over incarcerated people.

If you want to reduce recidivism, better to pay for their work so they see value in an honest day's work. What we've got now only teaches prisoners that we've got them over a barrel.

Forced sex, or torture, or other horrible things are inhumane and unacceptable. Being required to sit in a cell without leaving after you have been convicted of a crime is something that society has decided is acceptable. It seems like being required to help out with serving lunch or mopping the floors is more like the latter than the former.

Forced labor is also inhumane and unacceptable. "I ate your lunch because it was just sitting there in the fridge" is an even lesser moral injury, but that doesn't make it right.
