It should be noted that when Amazon's CEO published his note about return to office, increasing productivity was not listed as one of the reasons. Company culture, ad hoc meetings, serendipity, were the listed reasons. So it sounds like companies are not optimizing for productivity, they are optimizing for innovation. Whether these things contribute to innovation is still up in the air. I personally think happier employees will be more innovative, but have no data to back that up.
