TL;DR: I've been more productive at home than the office and want to keep it that way.
The best part is that I have an actual home office with my own door that I can close for meetings. Having my own space is key. I can turn on some productive music (classical, mostly, but Christmas music is coming soon) and get into my engineering zone. (Too often a certain co-worker's distracting music -- lyrics, blegh -- was too loud to compete with.)
I like clocking on at 0600 ET and off around 1500 and not wasting time packing food for the day or commuting (even though it was only ~9 miles). Coworkers know I'm not likely to attend a meeting at 1500 or 1600.
It was especially great in the spring, when the kids' "virtual schooling" was new and very unstructured, and the summer (no school). Not so much since classes restarted with live whole-class video chats via Teams -- especially since I'm the building's IT guy -- but things have gotten better (especially with a $35 Wi-Fi hotspot to supplement the crap radios in AT&T's modem).
But here's the context: I do what I want and don't give a darn about who else is working or when.
Example is a 9/80 work schedule -- my former employer had official policies with ~90% of the employees taking every bi-weekly payday (Friday) off. When I switched, I told folks "I'm still doing that" and found the timesheet tricks to do so. Everyone was reasonably flexible. Right before the pandemic, current employer started an official corporate 9/80 policy, which hasn't really taken off, and I now get my non-payday Friday off, and my coworkers don't seem to appreciate my preferences, but I care more about my family time and "work balance" than pleasing them. I take those Fridays off and otherwise flex my schedule any way I need, and will continue until I'm threatened with termination.
For now, I have an instant defense: the CEO's company-wide policy is "remote if possible until the end of 2020" (and I expect this will be extended). After that, I might do one or even two days a week in the office, but it's going to be difficult because we lost (via a collision) one of the two family cars a few weeks back.
And if those weren't enough reasons: One coworker who was mostly in-office contracted COVID and other office-dwellers had to self-quarantine at home anyway. HA! That's what you get for not following CEO guidance. I'll stay unexposed at home, thank you.
