My current employer went from rigid 100% office attendance, a là Office Space and cubes and dress codes and Nina, to 0%, overnight, for COVID. They sold most of the space but for 2 permanent and 4 more hotel spots, they have meeting spaces and a revolving receiver assignment for packages, but the entirety of the staff is effectively remote since the state of emergency was declared. Transition was fast and furious and they survived with most of their sanity intact. They wrote remote-first into the union contract, and quietly mention it's from anywhere in the country.

Reduction in space doesn't mean reduction in staff nor mandate. We're only growing.

Just, look for other indicators.
