To be honest, I wonder if they could band together and challenge this in court. While companies get tons of leeway, you might be surprised that there's sometimes protection.

Even if legal, what Musk is doing is incredibly sleazy. The employees agreed to work on certain terms. Then he demands they agree to different terms. Seems sketchy, but I think I know what they'd argue.

It's just a really creepy thing. I don't think I've really seen or heard of it elsewhere. You work for me, so sign here for different terms, or you lose your job.

I do know that it's probably legal in most jurisdictions for CEOs to just dictate new work conditions, after hiring (though it shouldn't). However, it doesn't normally come in the form of a button you must push to agree with him, "or else". Usually you have a meeting where you explain the plans moving forward... it seems companies that are scared of being sued do this.

I can't imagine this is a legally prudent move. We should enact laws that specifically target CEOs that act like cartoon characters. Of course, that would just let them be more secretive or quiet.
