No, but here's the catch that I learned about: if you're assigned to an office, they can make you go into that office at the same frequency as in-office workers

No, but here's the catch that I learned about: if you're assigned to an office, they can make you go into that office at the same frequency as in-office workers. You'd basically have nothing in writing that states you're a remote employee (I specifically asked the recruiter about this, and he confirmed). Otherwise why would being fully remote need "special approval"? That doesn't make any sense.
