Actually it's worse than that.  4 shifts aren't quite enough for a 168-hour
week, even before you allow for vacations, sick leave, and the inconvenient
fact that humans need to sleep roughly the same 8 hours in every 24 and
can't be rescheduled daily.  The standard rule of thumb for all-hours jobs
like police is that filling one 24-hour 7-day position requires hiring five
full-time people.
