I Felt like adding a couple of prison jobs as so
Warden
Head of the prison, would have to make prison rules, review inmates criminal record and decide were to put them, have to control prison funds/prison groups(such as rehab or job centers), have to send reports every month on prison status to government officals(plus more)
Prison Architect(ignore reference and hang in there)
Would be in control of certain prison deigns at certain times(appointed by warden), responsible for making sure required equipment is ordered, responsible for making sure broken equipment is fixed, and that all equipment is up-to-date, responsible for hiring builders/building supplies for projects, fixes, ect.
prison guards
guard certain parts of the prison, enforce rules set by warden, make sure prisoners behave themselves
please comment if you have any more job ideas or extra job duties you would like me to add! :)
