In normal society, people earn money within the legal confines of the society they are in. If you're a thief and trying to skirt that normal "earning of money", which is what normal people equate to "work", your work is scheming a plan to obtain the item without getting caught and possibly how to fence the item for money if you're not just using the item directly.

Equating "work" as the repercussions is looking at things in strange way. That's just punishment for "working" outside of the legal confines of society.
