Turn to wise man for employment (5)
I believe the answer is:
usage
'for employment' is the definition.
(synonyms)
'turn to wise man' is the wordplay.
'turn' becomes 'u' (a 'U-turn' is a kind of turn).
'to wise man' becomes 'sage' (sage is a kind of wise man).
'u'+'sage'='USAGE'
(Other definitions for usage that I've seen before include "Usual practice" , "Accepted or habitual practice" , "etiquette" , "Habit" , "Treatment, practice" .)
