What about simply, the early birds take the early shift and the night
owls take the late shift?  Between the two, you cover a larger set of
hours, get more accomplished and have someone on deck either
protecting the tribe or getting stuff done.  That's how it is in our
house.  (I'm the night owl, BTW, although that's only in comparison to
my spouse.)
