op shop

I'm a little stuck... Click here to teach me more about this clue!

'philosophers don't relish working in a charity' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'store' is the wordplay.
I cannot quite see how this works, but
'store' could be 'shop' (synonyms) and 'shop' is found in the answer.
The remaining letters 'op' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
