IN PRISON ...you dwell inside a stable concrete structure designed to withstand riots and most forces of nature. It is guarded by armed federal police who can kill zombies.
AT WORK... you dwell inside an all glass building able to withstand no riots, minimal weather hazzards and is guarded by a rent a cop with a tazer who cant repel 5 year olds.
IN PRISON ...sex finds you (sometimes in the form of rape)
AT WORK ...you have to hunt for sex (which isn't free sometimes)
IN PRISON ...you can shower and sleep
AT WORK ...there is no shower, and sleeping will get your punished.
