'where leader seemingly subservient lightweight agent said go to work' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'lightweight agent said go to work' is the wordplay.
'to work' is an anagram indicator (letters worked into a new order).
'lightweight'+'agent'+'said'+'go'='lightweightagentsaidgo'
'lightweightagentsaidgo' anagrammed gives 'THE TAIL IS WAGGING THE DOG'.
