My own office did an internal study in the year after the pandemic started and found the reverse. People with home offices started working sooner and got off later. More work got done during the day at home. Employees were generally more productive out of the office. And during moments of crisis (the Feb freeze/blackout and several nasty storms) more people were actually available on short notice than would have been in an office model.

We're still doing partial work-from-home to this day, in fact. It helps with employee retention and is generally better for the company at large.
