One size doesn't fit all - and that's exactly the issue with office work. After years in IT business I know exactly what are my "peak" hours/time and when it's better not to do anything work-wise and just focus on something else. Forcing me to work specific schedule in a specific office setup is no go for me. Plus other things like being able to exercise instead of my commute, eat healthy, use my equipment and tools I prefer, being able to refocus when I need and take advantage of my biological peak/down hours/time made me super efficient and productive.
