Swings and roundabouts. I think a lot comes down to the team around you when you start a job, a decent team will build up the new people to a decent standard whereas a dysfunctional department will drop new people in at the deep end leaving them to sink or swim.Seriously mate there is no way I could do your job, I'd end up in the jail for battering the kvnts. Being a Polis was far easier I reckon.
Part of the reason I go out of my way to help the young trainees, if I can beat some cynicism into them early they might stick the job out longer than 24 months.
Edit - a mate who used to be a teacher is now a prison guard, reckons it's much the same but now he's allowed to hit people.
