Finance worker shot (8)
I believe the answer is:
backhand
'shot' is the definition.
(type of shot in tennis)
'finance worker' is the wordplay.
'finance' becomes 'back' (backing is a kind of financing).
'worker' becomes 'hand' (hand is a kind of worker).
'back'+'hand'='BACKHAND'
(Other definitions for backhand that I've seen before include "Tennis stroke" , "Writing style" , "tennis side" , "flourish in court" , "shot, sportingly?" .)
