Release assistant to take on job (6)
I believe the answer is:
parole
'release' is the definition.
(I know that parole is a type of release)
'assistant to take on job' is the wordplay.
'assistant' becomes 'PA' (personal assistant).
'to take on' is a charade indicator (letters next to each other).
'job' becomes 'role' (a job is a role or position).
'pa'+'role'='PAROLE'
(Other definitions for parole that I've seen before include "Temporary release (of a prisoner)" , "Lop ear (anag.)" , "limited release" , "Early release on promise of good behaviour" , "Temporary release on promise of good behaviour" .)
