There are plenty of us who became extremely productive and can finally enjoy life rather than constantly play the spectacle in the office or sit in traffic for hours. And don't get me started on the ones who are neurodiverse or have any kind of disability.
During the WFH era which for me was 2017 - 2022, I made up for the 9 - 10 hour workdays by not using up PTO for doctor appointments, car repair shop trips, and so on. This worked reasonably well - and nobody minded if I was getting my oil changed or sitting for an hour at a doctor’s office lobby and responsive on Slack. It was a compromise that worked reasonably well.
We also carved out time for people to pick up/drop off kids at school. In exchange, the work day expanded from basically 8 to 5 or 9 to 6. Everyone was comfortable with this. I certainly didn’t mind people on my team doing this at all and really appreciated the extra availability - we just knew to plan around the school pick up and drop off times, which were also in the calendar as a recurring meeting.
What’s not working now is imposing RTO and trying to have the same extended hours. Sorry, but no, I’m not going to drive in from 7-8, work from 8-6 without breaks, and then drive home from 6-7.
