Maybe people at home are 25% less productive.
They are finding people are generally as, if not more productive at home. People working in offices waste a ton of time (in an office work environment. Things like customer support/ service and contact centers don’t see much difference.)
My wife has worked from home since March 2020. She never wants to go back. No politics. No “what did you do this weekend” crap. And no having to be the “Office Mom” for the idiot kids.
