Back pay for draughtsman? (6)
I believe the answer is:
drawer
'draughtsman?' is the definition.
(someone who draws)
'back pay' is the wordplay.
'back' says the letters should be written backwards.
'pay' becomes 'reward' (I've seen this before).
'reward' in reverse letter order is 'DRAWER'.
'for' acts as a link.
(Other definitions for drawer that I've seen before include "Reward (anag.)" , "One who writes cheque; storage box" , "Sliding part in a piece of furniture" , "One signing cheque" , "Sliding storage space" .)
