Sure, but those documents you signed aren't going to guarantee that you can work remote forever (like parent comment suggested).

Having a true employment contract that guaranteed a duration of work with full remote work could only happen if such a contract stipulated consequences for breaking that deal.

The contract would have to say something like "If employer changes the nature of this agreement, employer agrees to pay 100% of owed salary for 12 months". Those employment contracts do exist but they're generally only for key employees, not your average remote worker.
