Reward — our men earn it corruptly (12)
I believe the answer is:
remuneration
'reward' is the definition.
(I've seen this before)
'our men earn it corruptly' is the wordplay.
'corruptly' is an anagram indicator.
'our'+'men'+'earn'+'it'='ourmenearnit'
'ourmenearnit' anagrammed gives 'REMUNERATION'.
(Other definitions for remuneration that I've seen before include "Money as reward" , "Money paid for work or a service" , "Payment - a minor tenure (anag)" , "Pay - our men earn it (anag)" .)
