Pole in wages spoof (6)
I believe the answer is:
parody
'spoof' is the definition.
('parody' can be a synonym of 'spoof')
'pole in wages' is the wordplay.
'pole' becomes 'rod' ('rod' can be a synonym of 'pole').
'in' means one lot of letters goes inside another.
'wages' becomes 'pay' (I've seen this before).
'rod' placed within 'pay' is 'PARODY'.
(Other definitions for parody that I've seen before include "Make a mockery" , "Humorous misrepresentation" , "Satire - burlesque" , "Takeoff" , "Spoof, lampoon" .)
