My workplace is 80% remote, but not in the way you might think.
Just about everyone works from home 4 days a week, and comes into the office one day.
It expands the hiring pool by a pretty significant amount, one of our devs is 2 hours away (4 hours round trip, and he still commutes less than his wife does every week), it lets us get a lot of the "face to face" benefits done in one day, and the rest of the time is remote.
We do also have a couple fully remote, and a couple "always in office".
It works out nice though as we tend to remember to include the "always remote" people on our in office day because most of us know how much it sucks getting left out.
