My whole office went to WFH as soon as the pandemic started, the plan was to move back to the physical office as soon as possible, but there was so much resistance in the company that eventually the owners sold off the building and we never went back.

As for productivity, I was in charge of transitioning my team and ensuring they weren't slacking. I had the exact opposite problem with 9/10 out of them, mostly everyone was working too late and putting in time off the clock just because they were bored. We ran out of work to do every week and started taking on new tasks for other teams.

Except Terry, he got a second job and tried to work both at the same time. He never appeared on camera in our meetings because he was at his other employer. It took me a bit to figure out something was off, when I confronted him he abruptly quit. He was a sour and deeply repressed dude and after he left everyone celebrated.
