I work from home one day a week, and honestly, I'm not sure I'd want to do more than a day or two each week. It's my most productive day by far, but the isolation feels unsustainable for me.
Alternatively, if you're set up to work remotely every day, you come to work the same way you would in an office and you don't "wait until so-and-so is back in person" to get stuff done. One day a week might be a good experiment, but it's definitely not an indication of the way you would be working if it were full time and it's definitely not the same thing as remote work in my experience.
Until everyone you work with works remotely (or "like they are remote") it is difficult to simulate what that work can look like when it gets going well.
I just started a new role where video calling is engrained in communication. If you're going to be hashing things out on Slack for 10+ minutes, you might as well get on a video call for half the time.
