Most of the people I worked with did not have jobs that could be done from home - they had to be in the labs and facilities. Only a few of us could telework.
I retired before I would have had to go back into the office; but I probably wouldn’t have minded. Still, I know I was personally more productive working from home. And telework didn’t change much anyway - I had always received most requests and orders by phone or email anyway.
That lasted less than 2 hours as I'm primarily a field engineer, but have other critical “chores” in the lab and more.
I was one of the few that couldn't change their routine for several reasons, up to and including “national” infrastructure “servicing”. Had to keep everything running, and fulfill many sudden demands directly due to work from home infrastructure maintenance and upgrades.
It was weird visiting customers with basically empty roads here in Southern California. I also got the honor of not sequestering when people were getting sick around the area, wondering if everyone I had to meet with would give me the virus, but didn't catch it again that year, and I likely owe that to natural immunity after getting Covid at the outset.
Never got vaxed, may have caught a weaker variant once or twice since then, but nothing significant.
Got exposed to it at an illicit impromptu Christmas party later that year, but aside from getting chewed out by the boss, no big deal.
Strange years.
