I am in that 40%. During the pandemic when things moved to remote, I sold my suburban home and moved to a regional area. Truth be told, I was already working remotely anyway. I did occasionally go into the office, but everyone found that remote work worked so well, they just decided to give people the option. It's not super regional, but where I am there is no sewerage, so I have a waste treatment plant (a fancy septic tank) and my kids have a yard, everyone is happy. I still have a 1gbps internet connect that is very reliable, phone reception can be spotty, but we love it.
Remote work is not only a way of life now for me, but my household. Our family moved to a new area and while it was a big adjustment for us, everyone is so happy. When we were living in our shoebox of a house, it was nice to be close to the beach and brand name stores, but everyone seems less wound up. The traffic isn't bad, it takes 15 minutes to drive to the town centre which has a reasonable sized shopping centre and nice restaurants. Public transport isn't great, but there is transport.
The best thing of all about working 100% remote is the flexibility. Some days I need to do the school drop off and pick up, I just let my employer know and it's not an issue. Sometimes I'll start earlier to compensate or work through lunch. I never miss packages anymore (I don't miss going to the post office to pick up packages). The postal service doesn't leave everything at your doorstep anymore like they did during the pandemic. If you need to sign, someone has to be home or they're taking it to the post office. I get to eat lunch with my wife, do some chores around the house. Sometimes I will get away from the computer and go out and push the mower to cut the lawn.
If I were to quantify how much we have saved in child care costs, it would be immeasurable. One child costs us $70 per day for childcare. There have been days when my kids have been sick and I was working from home, so I could help out, but also work on my laptop (even if it's beside them). When I finish work, I can go outside and kick a ball with my son. Remote work has been tremendous from a family bonding perspective. If I were working in an office, my kids would only see me on the weekends as I wouldn't get home until it's their bedtime and I would be leaving as they were waking up.
The one thing people need to respect is not everyone wants or can work from home. And I think people on both sides of the fence should have the choice. Obviously, if you're applying at a company that only works remotely, then you waive the right to complain. But, if the company offers both, nobody should be forced one way or the other. Flexibility is now a perk.
