Promise Personal Assistant position (6)
I believe the answer is:
parole
'promise' is the definition.
(parole is a kind of promise)
'personal assistant position' is the wordplay.
'personal assistant' becomes 'pa'.
'position' becomes 'role'.
'pa'+'role'='PAROLE'
(Other definitions for parole that I've seen before include "(One's) word" , "Give Al rope when he's released early" , "Word - condition of liberty" , "Lop ear (anag.)" , "Promise - conditional release" .)
