Getting eventually employed again. You would be surprised how hard someone works knowing they get a chance to stay in this country compared to someone who was born here.

That sounds exploitative, and I'm surprised seeing this kind of sentiment on Hacker News, which, from my perspective, typically is in favor of worker rights

Of course it's exploitative, but I do see a longer grace period helping alleviate the pressure that such visa holders would face. I'm surprised that FAANG companies haven't really offered subsidized housing as long as the employees retain their jobs or meet certain performance metrics. That's another great way to ultimately exploit certain workers while seeming like a huge perk.

The "pro worker" stance here being people being unemployed losing thousand having to uproot their lives potentially with families being pulled out of schools etc?

I am not saying it's not exploitative nor arguing for it. The question was why would the US have an interest in this.

What's the use of worker rights if one is not given fair chance to be a worker again?

Avoiding that talent going elsewhere

Not much. H-1Bs are for filling in gaps in the job market. If the people can't get a job because they got laid off then we don't need these people anymore.
