Get on with some scallywag, re-employed (5)
I believe the answer is:
agree
'get on with' is the definition.
(thesaurus)
'some scallywag re-employed' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'AGREE' is hidden within 'scallywag re employed'.
(Other definitions for agree that I've seen before include "grant" , "Concur, acquiesce" , "Settle" , "Enjoy view in common" , "'Birds in their little nest . . . . .'" .)
