The problem with employee schedules where employees work in shifts is communication. At one place it was done using Excel as I'm sure it's still done today in many organizations. You always have two people trading shifts but never telling anyone. Then the one who was supposed to work doesn't show up they forgot they traded shifts. Human nature is half the problem.
