A cushy job (8)
I believe the answer is:
sinecure
'a cushy job' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sinecure that I've seen before include "Paid job involving little or no work" , "Office that involves minimal duties" , "Job for easy money" , "position needing little effort" , "A job that pays well for little work" .)
