Bribe sponsor to accept worker (10)
I believe the answer is:
backhander
'bribe' is the definition.
(I've seen this before)
'sponsor to accept worker' is the wordplay.
'sponsor' becomes 'backer' (someone backing or sponsoring something).
'to accept' is an insertion indicator.
'worker' becomes 'hand' (hand is a kind of worker).
'backer' going around 'hand' is 'BACKHANDER'.
(Other definitions for backhander that I've seen before include "Bribe - tennis stroke" , "Swipe" , "court action" , "strike" , "sweetener" .)
