When we were remote, my staff was nowhere near 8 hours a day. Our schedules are very dependent on our students (higher education) and their needs. Sometimes they would work 2 hours a day, sometimes 10. It was literally just like in the office, except they were free to do whatever they needed to do during their down time.
Old administration thought that wasn't good, because people were screwing around during the 8-5. I tried to explain that yes, that happened, but
a) that already happens in the office;
b) they're also working at night, on the weekends, and whenever the hell I need them to, and not complaining about it, or even being bothered by it
c) they're happier and MUCH more effective for the students.
No go.
