Hates also working with article (7)
I believe the answer is:
loathes
'hates' is the definition.
(loathing is a kind of hating)
'also working with article' is the wordplay.
'working' is an anagram indicator.
'with' is an insertion indicator.
'article' becomes 'the' (the definite article in English).
'also' with letters rearranged gives 'loas'.
'loas' placed around 'the' is 'LOATHES'.
(Other definitions for loathes that I've seen before include "Dislikes strongly, despises" , "Abhors" , "Detests" .)
