Pros
You are able to make a positive change to offenders by giving them options to become proactive and productive members of society. You teach them accountability for their actions with daily inspections of their living quarters, any programs and employment options they could pursue, and how to retain those close connections through letters and visits. You prepare them to return to the workforce by guiding them on grooming standards and how to interact with professionals, supervisors, and those they may find difficult to establish rapport with.
Cons
There is not enough time in the day to handle everything on your caseload. You have limited resources, classroom space, or employment options available for offenders. You have to make abrupt changes to your plans if the facility is on lockdown. Sometimes you have to be flexible enough to handle other responsibilities outside of your job scope.
