They just don't get that some people can't spread their time into perfectly equal slices of productivity. Remote work and flexible time has allowed me to work a big productive burst in the morning and in the late evening, spaced way more than 8 hours apart, with busywork somewhere in the middle. Probably wouldn't work this well if I had to do that in an office, in a single 8 hour (or 4+1+4) segment.
