Workplace boss I love (6)
I believe the answer is:
studio
'workplace' is the definition.
(I know that studio is a type of workshop)
'boss i love' is the wordplay.
'boss' becomes 'stud' (both can mean a metal decoration).
'love' becomes 'o' (love means zero in tennis).
'stud'+'i'+'o'='STUDIO'
(Other definitions for studio that I've seen before include "Film production company" , "Elstree area" , "Workroom for 27 down" , "Workplace for the practice of art" , "Apartment with one main room" .)
