I brought up concerns about WFH productivity once in another thread and quickly realized that many people on here do not want to discuss the facts and only want to consider anecdotal evidence in favour of WFH.

I'm glad to see that there are studies being published that show how certain companies are actually doing, rather than a handful of people loudly saying "my group is equally as productive WFH so no one should work from offices". I don't think those people are going to be so happy as more research is published and company leaders realize what is happening to productivity.

I'm confident that HN sentiment is a fantasy created by people who are barely working.

It varies dramatically by circumstance. I had coworkers who struggled with 3-4 kids and working spouse at home.

For me, my son is 9 and my wife was partially at home. No big deal for my productivity. For my sister, she sold her car and hired a nanny for a year.

Maybe if you do nothing but greenfield coding, but when does that ever happen? You'd need to be in a startup or a company with severe NIH that also likes to rewrite everything every few years.
