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.

Truck drivers with a clean driving record can trivially find another job.

Now if they are locked into some Uber-like scam where their employer financed "their" truck purchase it may be more complicated.

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.

You don't need to do anything. The IRS will fight this one for you.

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.
