Our big boss man stresses that while Covid has changed things in the short-term, we are NOT going to be a "full remote" type of company. I think he's saying that for the 70%+ of the company that really does need to be in the office every day. I work for a company that represents investors in affordable housing.
In my division there are folks that are 100% remote since they live in Denver, Austin, Tennessee, New York, etc. They are assigned a territory and visit the properties within that territory on a regular basis so they are always going to be remote. Then there's my little group that handles the assets during construction phase ONLY. So we travel all over the country.
But when we're not traveling, we are based in Irvine, CA. My boss actually relocated to Boise and that's been working out fine. My guess is that they continue to have us coming into the office 2x a week (I'm Monday/Wednesday) until that somehow proves inefficient. Which it won't.
The folks in accounting and such will likely, at some point, go back to a normal M-F 8-5 type of situation.
Right now I love 2x a week in the office. I get a lot done on Mondays. Tuesdays my wife works at Starbucks so I have to pick up the kids and make sure they're doing homework and chores. I do a lot of laundry on Tuesdays. I take a nap sometimes. I usually start happy hour around 4pm on Tuesdays too.

Wednesdays are good to get caught up.... and if I'm traveling it's usually on a Wednesday so there's another day that I don't go to the office. Thursdays are usually booked up with Teams video meetings. Fridays are relaxed and during the summer months they actually let us free at 1pm... which is awesome.
So yeah if there's been anything good that's come of Covid, it's this work environment. I love my job and this schedule is great.
