It works a bit like this in Swiss hospitals. Or at least used to. Might have gotten LEANed away. I have fond memories of christmas dinner as a child/teenager, not because of any religious affiliation but because it was one of the few times a year the family of six, three of which work in hospitals, spent a day or so together. There were few overlaps of free time otherwise. I don't remember the exact mechanics how it worked, but I think work schedules get set about 6 months in advance with some employee input about their preferences, and employees can to a degree swap shifts with each other. So e.g. it was quite common for people with kids to take christmas off, whereas young singles or from different backgrounds took new years or any other day.
