Waste of resources?
I don't understand what this would achieve.What difference would be made by having to quit your job in order to be a criminal? A 2 second hassle that nobody wants. It will make no difference.
then disable it to for unoccupied and off duty workers.
Disable /criminal for unemployed and off-duty people? How would somebody be able to become a criminal then?
Actually it is much more realistic than going to a marker and suddenly becoming a criminal. You can right now go and rob houses too without having to go to a sideway in the place you live in..
