Working remotely for a small company with a few people from around the world and it's going fine. We are in contact when we have to be. I can cut distractions when I need to. No open space office bulshit.
I was raised on IM. I'm fine communicating like this. If I need to talk I can always call someone.
In any case, you need a space to work. If you WFH you should have a space for work. I strongly believe that employers should pay you more so that you can afford an additional room. This should not be a cost cut for the employers. They should just pay you instead of paying the insane office rent.
WFH is simply different from working at an office. It will be hard for some people to learn a new way, but this major change could even redesign our cities.
