I mean it sounds like she knows what job's she's able to do while on worker's comp, without losing it. Not sure why anyone would care what she's doing unless it adversely effects them. If she's injured, she probably has doctor's bills to pay. Not to mention other bills, and given that Covid screwed over pretty much everyone. And then you have gas prices. In many places you're allowed to take other jobs while still collecting workers compensation, and usually doctors will tell you if a job you take will disqualify you or not. She might not be able to make it on Workers Comp alone.
"Tradition" is just a word people use to make themselves feel better about being an asshole.
