That’s easy to say if you can trivially find another job. If they’re concerned about that and don’t want to be in a tax case (which seems extra unappealing for someone who spends most of the day driving) they probably won’t - and that’s what those companies are banking on.
California regulatory requirements basically shut down drivers owning their own trucks: the cheap old diesel trucks aren't in compliance anymore. So there's a lot of scummy leasing arrangements for the newer more expensive trucks.
That’s what the situation in this thread sounded like: those companies must have some kind of lever to force exclusivity and I’d assume it’s something like a loan.
The question is whether they are confident enough that this will be true, not lead to retaliation, and some consequences will happen. If not, a lot of people might feel they’re trapped.
I dunno.. maybe the government should start an advertising campaign, but that would imply that they would be able to put individual interests above those of their corporate overlords.
