Disinclined to have acted as a model after work (7)
I believe the answer is:
opposed
'disinclined' is the definition.
(similar in meaning)
'acted as a model after work' is the wordplay.
I cannot quite see how this works, but
'model' could be 'pose' (model can mean to pose) and 'pose' is found within the answer.
'work' could be 'op' (abbreviation for opus) and 'op' is found in the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to have' is the link.
Can you help me to learn more?
(Other definitions for opposed that I've seen before include "likely to refuse?" , "like foes" , "Took contrary position to" , "Withstood" , "Stood against" .)
