Just for completeness, the US has its own flavor of issues here in its prison system.

Just 23¢ to $1.15 is the typical hourly pay [1], and work is not always voluntary and up to the same employee protection/safety standards as true employment [2].

Labour sourced from the incarcerated creates problematic incentives in law enforcement.
