Amazon is famous (or maybe infamous) for always making data driven decisions. So it's curious... and very telling... this Amazon exec admits he has no data to back up return to office policies.
Either
(1) there is no data, or
(2) there is data, but employees won't like it, so therefore Amazon won't share it. E.g. data indicating it's easier to control employees who are in office, and location dependent, and much harder for them to quit, for example.
Number (2) is the most likely scenario, in my opinion.
