That is mechanically different. All the leverage is in the hands of the companies seeking out cheap labor in that case.

I actually don’t think it should be like the poster you replied to suggested where the immigrant employee in question needs to maintain employment.

I would advocate that we structure employment visas like we do marriage visas which would mean we calculate whatever the total cost of the drain on our system would be if the new immigrant wasn’t working, charge the company that much to have them enter, and then the employee is free to quit immediately if they feel it’s in their interests
