The norm is 9-530 (or was, probably isn’t anymore). Taking things like school runs out of the equation (these too can be changed in this scenario), what hours do you work best?
I’m better later in the day and always have been. I also find working late at night easier to get on without interruptions. I’d shift start times forward by a couple of hours and probably do 5-6 hours in the 11-7.30 window and 2-3 hours later on. This also assumes you are literally just doing the hours you are employed to, rare I know.
