Employees have reported finding it easier to find a healthy work/life balance, feeling more engaged and less stressed by the shorter week, and enjoying their jobs more as a result. Less obvious benefits might also include fewer overheads, especially if the office is empty for an extra day, and a fewer commutes meaning a lower carbon footprint. I don't think it would result in fewer overhead. An empty office is actually more of a waste. You're still paying rent even on days when your office is empty. And with longer working hours, whatever savings you get from that extra day in utilities could be cancelled out by the longer operating hours. But I agree that a 4 day work week would make social distancing easier for employees. And the reduced in traffic do help business improve employee morale and easier access for customers.
