Colorado voters passed Amendment A, a ballot measure touted as an end to slavery in state prisons in 2018. The amendment eliminated the penal exception clause, which allowed the state to use forced labor in addition to incarceration as a punishment for crime.
Colorado was the first of eight states to repeal its penal exception clause. Advocates for the policy change hoped it would prevent forced labor for little pay. Colorado pays incarcerated workers between US$0.33 and $1.61 per hour for maintenance jobs such as cooking, cleaning and groundskeeping.
