Workman needing new ear doctor (9)
I believe the answer is:
decorator
'workman' is the definition.
'new ear doctor' is the wordplay.
'new' is an anagram indicator.
'ear'+'doctor'='eardoctor'
'eardoctor' is an anagram of 'DECORATOR'.
'needing' acts as a link.
(Other definitions for decorator that I've seen before include "Painter perhaps" , "Worker embellishing a property" , "chap giving medals?" , "Handyman" , "One doing up a house or room" .)
