work...absolutely no way Zoom Calls would work effectively...for me, I harken back to a discussion with a colleague who observed that production goals started being missed after quarterly gatherings of worldwide group representatives were replaced by the predecessor to 'Zoom Calls'...he claimed that the 'After-Meeting' person-to-person gatherings allowed for deeper understanding of issues that could not be expressed in the context of a public video forum...admittedly this situation was not the same as day-in-day-out attendance, but it illustrates the value of human contact.
Another example for me...and a nod to Iggle...were Thursday get-togethers at the local "Watering Hole" where Manufacturing, Marketing and Engineering leaders and staffs would "Bond" and reach agreements that again, couldn't possibly be done over a "Zoom Call"...then, of course, there were the opportunities (especially in the early years) ofr getting helpful input from the 'old hands' on a new design idea.
IMO, flexibility is great and should be accommodated, but when meaningful benefits from in-office attendance can be shown, all hands should be "flexible" to that notion.
