Take on work (6)
I believe the answer is:
employ
I believe this clue is a double definition.
'take on' is the first definition.
(I've seen this before)
'work' is the second definition.
(thesaurus)
(Other definitions for employ that I've seen before include "Keep (someone) occupied" , "occupation" , "Utilize" , "Take on - recruit" , "Give paid work to" .)
