In Europe it's the other way around: the businesses employing folks with no right to work get fined to death, with no direct repercussions on the workers (except they lose that income, which is another discussion)
Except the farm businesses complained, and the Trump Department of Labor rolled back a bunch of the protections. For example, apparently a sticking point was the requirement that vehicles transporting visa holders have seatbelts for all occupants, so that was eliminated. Another was the requirement that workers be allowed to have guests visit them on employer-provided housing; an often-cited example is worship services provided by a priest. Also rolled back, too onerous.
This is all being stressed at historically high levels as immigration crackdowns continue. Essentially, food production in border states is increasingly forced to go through this visa program that has terrible oversight and protections that I consider below-par. It's not a sexy issue to yell about with a megaphone though.
