Does anyone know how equity is affected by remote policies at most big tech companies? I think that perhaps it isn't? Companies take back unvested equity if you're terminated or resign, but I don't think I've seen anything in my equity agreement docs that would let them take some of it back for a cost of living adjustment (though they could probably adjust the terms of new equity grants going forward). If I'm hired in a low CoL area I bet they adjusted for, but what if I was hired in the Bay Area and then move? Am I crazy or is there perhaps a huge loophole here, at least in the short term, that nobody is talking about? Let's look at a senior engineer (E5) at FB on levels.fyi - $380k total comp comprised of $196k base, $30k bonus, $154k equity. If your base & bonus get cut by 50% by going remote but you keep the equity, that's still $267k a year so your total comp has only been cut by 30%. And hell you could make up a significant amount of that in taxes alone. For a staff engineer or manager at E6/M1 level it's even more dramatic - $578k total comp down to $436k, which is only a 25% decrease and just a stupidly high compensation for somewhere with a low cost of living where, say, you can buy the equivalent of a $3M silicon valley home for well under $1 million.
