Easier to track worker productivity (this is actually wrong, is significantly easier to track productivity done remotely, but management has lost out on traditional visual cues for productivity)
These corporations either own the real-estate, so having them empty greatly reduces the value, or are tied into long term leases they can’t get out of.
Mandating a RTO is also an easier way to offload staff without doing layoffs, as many will just leave.
It’s easier for people in positions of upper management to “build work culture” and “team development”
None of this are valid to you, but I imagine this type of thinking makes sense to management
