Indeed, answering my own question after reading more of the long, but well-written specification: a more concise, but equivalent version, is of course: 
 -
  date: 2005-06-01
  team: [ Jack, Jill, Joe ]
  boss: Clara
 -
  date: 2005-06-02
  team: [ Harry, Hillary, Howie ]
  boss: Victoria

Even more concise, each day can be made to fit on one line: 
 - { date: 2005-06-01,  team: [ Harry, Hillary, Howie ],  boss: Clara 
+   }
 - { date: 2005-06-02,  team: [ Jack,  Jill,    Joe   ],  boss: Victor
+ia }

which makes it more readable as a table.

I wonder if you can simplify even further, by factoring out the hash keys? Something on the order of: 

# INCORRECT YAML SYNTAX
 - { date:,      team:,                     boss:    }
 - { 2005-06-01, [ Harry, Hillary, Howie ], Clara    }
 - { 2005-06-02, [ Jack,  Jill,    Joe   ], Victoria }

Probably not.
