Department assist job slots would be great.
Security Trainee? Department pet for the HOS or warden to take to the firing range to train!
Medical assistant? I once offered to take a newbie as my surgeon trainee, he did great and fun times was had by all, except the patients under his meatgrinder surgeries but he had to learn!
Engineering trainee? No more busted teslas or singulos (optimism)! Let him see how it`s done first!
Service dosn`t really need any assistant slots, as they are, by nature, rookie jobs.
Command underling? HOP or Cap`s little pet, fetch coffee, watch them boss around, get a grip of things.
