There’s been data on this, and RTO has overall actually lowered productivity. The productivity numbers this year are worse than last year and way worse than the years where everyone was wfh with Covid.
Is there some advantage to working in person? Sure - but most of these things just naturally take place virtually now so, as others have said, you end up with most teams just doing all meetings virtually anyway…which does overall make being in the office pretty much pointless.
Due to the added stress, attrition, and employee anger caused by RTO policies you end up with lower productivity due to quiet quitting, malicious compliance, etc.
There’s studies and numbers coming out about this now from independent sources - there’s a reason why most companies refuse to back up RTO with actual data…it’s because the data doesn’t support their narrative.
Ignoring the data for your own bias has proven to be foolish throughout history.
