As someone who interacts with PAX personnel every day (or at least tries to) for work purposes and speaking of my own personal experience, I can say that WFH is a bust! Constant flow of unreturned calls and emails, never able to get answers from people, no-shows in meetings, on and on. Local stores PACKED at all hours of the day. I have 3 GOV employees in my neighborhood that are outside their houses doing yard work throughout the work day.
No one will EVER convince me that WFH is more productive. Not from what I have seen, heard, and experienced on a day-to-day basis.
