Expert forced to accept work (9)
I believe the answer is:
Here is my best explanation:
'expert' is the definition.
(I've seen this before)
'forced to accept work' is the wordplay.
'forced' becomes 'prised' (I've seen this before).
'to accept' indicates putting letters inside.
'work' becomes 'act' ('act' can be a synonym of 'work'**).
'prised' placed around 'act' is 'PRACTISED'.
