I didn't realize how much I love working from home till the pandemic began.
Last spring, I left a company I'd been at for five years and had made several friends at because they wanted us to return to the office. I ended up landing at an all-remote subsidiary of a multinational that's super cautious about covid and hasn't even started to reopen their offices at all aside from a small handful of people who do shipping and receiving and need to do physical stuff in person. I don't regret it one iota. I ended up getting a drastic pay increase and a seriously more impressive title out of the switch.
Back in October, I went out drinking with my former boss and he told me my old company cancelled their return to the office and went all-remote again when the delta surge started. I'm enjoying my new company too much to go back, though (and, no, they haven't replaced me, and that's a long story).
Some clarification on the subsidiary I work for: they were remote-first even before covid, and while they had an office, nobody was required to work there in person even well before the pandemic started. While our parent company wasn't remote-first, as soon as covid began, they immediately told my subsidiary's landlord that they wouldn't be renewing the lease. I've also been told that the parent company has 100% committed that all meetings will be Zoom-only forever even after offices reopen, because they've found that, as a multinational company, Zoom-only meetings have solved a problem where, pre-covid, if a team had 1-2 members in a different office than everyone else, those 1-2 members would be marginalized on the team and cut out of major decisions. Zoom has been the great equalizer.
Edit: Oh yeah, the best part is that I'm in Texas but everyone else on my team is on the east coast. So I get to work from 8-4 and then close my laptop and enjoy the rest of my afternoon. Getting off at 4 every day has done wonders for my mental health.
