He will get arrested only if he VIOLATES the order. Which is pretty much the whole point. His incarceration, or lack thereof, is entirely in his hands. Following the order is very simple. He can't get arrested by mistake.
There is no reason his job would have to know about the order unless he chooses to tell them. The only exception would be police or certain other sensitive positions. You said he works at a minimum wage job so it's a non-issue.
I don't care how long you stayed with him or what you endured--you don't deserve to be afraid or put down or humiliated. Period. End of story. The fact that he may have had a bad childhood doesn't mean he gets to take it out on you.
This is about protecting yourself and your family.
