What kinds of work do inmates do in prison? Are there jobs that sometimes are done without close supervision, for example, cleaning work that inmates do outside the cell or cell block?

Most inmates are required to have a job. There is plenty to do for those that are inclined to get into a routine that will make their time fly. The kitchen requires a lot of staffing, the orderly crews clean the prison, landscaping keeps the grounds manicured, commissary needs people, the chapel, the rec hall, education, the library, the barber...all require inmates to run their departments.
