Note that this isn't time-of-day consistency for working hours. That's nice, but what you really need is consistency for off hours. It's not terrible if the worker's scheduled hours jump all over within a 13-hour window as long as the worker knows that the remaining hours are usable for consistent sleep. The employee ought to be informed of their down time. For example, suppose the worker gets 6-hour shifts. It's fine to start at 3 AM on some days and at 9 AM on other days. That leaves a consistent 3 PM to 3 AM that they get for sleeping. Some days they work right after they wake up, and other days they start later.
