I’m sorry but your conclusions you drew aren’t in line with reality, specifically at my organization.

Ego and sunken cost were the main reasons at least at my workplace to reimplement back to work orders.

The majority of higher level management were not able to pivot to a remote scenario and were not willing to invest in the training and additional tech infrastructure necessary to convert to remote by design. It would have required deep restructuring and loss of middle management positions.

Our organization had multiple decades long leases that were signed in 2018. The employer also received heavy lobbying from municipal businesses and government to return to office. A big reason for that was the calculation that a lack of in office presence would cause financial damage to the downtown sector of my city.

There are many facets to this issue and none of them have to do with actual employee productivity.
