Resist model going after work (6)
I believe the answer is:
oppose
'resist' is the definition.
(I know that resist is a more specific form of the action oppose)
'model going after work' is the wordplay.
'model' becomes 'pose' (model can mean to pose).
'going after' says to put letters next to each other.
'work' becomes 'op' (common abbreviation for 'opus').
'pose' after 'op' is 'OPPOSE'.
(Other definitions for oppose that I've seen before include "match" , "Refute - confront" , "Resist, go against" , "Resist or fight against" , "Argue against" .)
