Hireling (6)
I believe the answer is:
minion
'hireling' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for minion that I've seen before include "Dependant, underling" , "Fawning servant" , "An archaic servant or inferior (6)" , "Servile favourite" , "Servile assistant" .)
