Part of orchestra detests work (5)
I believe the answer is:
trade
'work' is the definition.
(thesaurus)
'part of orchestra detests' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'TRADE' is hidden within 'orchestra detests'.
(Other definitions for trade that I've seen before include "Barter or swap" , "Commercial dealings" , "Commercial exchange of goods and services" , "Business - deal" , "Business - (kind of) wind" .)
