Recruit; utilise (6)
I believe the answer is:
employ
I believe this is a double definition.
'recruit' is the first definition.
(thesaurus)
'utilise' is the second definition.

(Other definitions for employ that I've seen before include "Use or give job to" , "Take on - recruit" , "Utilize" , "Put to use" , "Use or take on" .)
