I guess I can understand why Musk wants employees back in the office 40 hours/week. It's really difficult (but doable) to manage employees from afar. Management has to be properly trained on how to supervise geographically separated employees to maintain productivity. That means a lot of extra work for the managers and they push back and advocate for a return to the pre-pandemic model.
I was recently reading an article claiming Fortune 500 companies were getting an average of seven hours of productive work out of an eight-hour work day, pre-pandemic. But during the height of the pandemic, the authors estimated that fell to slightly under five hours/day ... primarily because managers did a poor job of setting goals, laying out tasks with realistic deadlines, and holding employees accountable.
