From the original poster's link: "More than 75% of workers told ACLU researchers if they can’t work or decline to do so, they are subject to punishment ranging from solitary confinement to the loss of family visits to denials of sentence reductions." If they can work, but decline to work, shouldn't there be a consequence?
"The authors of the report are calling for extensive changes around the use of prison labor, including ensuring that such work is voluntary and provides workers with the same wages and protections granted to other workers as well as work programs that give incarcerated workers marketable skills and training." Why should the work be voluntary and pay equal to outside jobs? Folks outside the prison system have far more expenses and budgeting issues. I do believe that if they have no marketable skills, they should be trained.
As a sidenote: The workshops for the mentally retarded and developmentally disabled also pay pennies an hour. Most of these people have little say in their placement and are unlikely to ever live independent lives. They do, however, show pride in receiving a pay check and planning their purchases.
