Service folks almost always work in shifts already, many are part time. One of the benefits of moving up the ladder is to get holidays off. I think this is the only way it could possibly work. Agree that most people should have say, Sunday off, but there are many import things that must have 24/7 or close to it coverage. Groceries (every day), medical personnel, firefighters, etc. Lot's of nurses work 3*12hr shifts per week for example.
