If you were explicitly hired into a remote role and they decide to try and force you to come in, that's a substantial change to your working conditions akin to constructive dismissal.

Depending on your state, you may be able to get unemployment from this situation if they fire you when you refuse this change to your role. The company will always lie about the circumstances but I've seen people still get unemployment out of it. This is much easier to demonstrate if you live far away from the office.

It is, effectively, a layoff that they want to avoid paying unemployment for.
