Owner of business backed worker accepting trophy (8)
I believe the answer is:
occupant
'owner' is the definition.
(thesaurus)
'business backed worker accepting trophy' is the wordplay.
'business' becomes 'co' (short for company).
'backed' says the letters should be written backwards.
'worker' becomes 'ant' (worker is a type of ant).
'accepting' means one lot of letters goes inside another.
'trophy' becomes 'cup' (cup is a kind of trophy).
'co' in reverse letter order is 'oc'.
'oc'+'ant'='ocant'
'ocant' going around 'cup' is 'OCCUPANT'.
'of' acts as a link.
(Other definitions for occupant that I've seen before include "Inmate" , "Insider" , "Inhabitant, resident" , "Person residing in a property" , "Tenant - resident" .)
