Earnings once I'm sacked? (6)
I believe the answer is:
income
'earnings' is the definition.
(I've seen this before)
'once i'm sacked?' is the wordplay.
'sacked?' is an anagram indicator.
'once'+'im'='onceim'
'onceim' with letters rearranged gives 'INCOME'.
(Other definitions for income that I've seen before include "Coin me! (anag)" , "Returns" , "Money gained over time" , "Financial gain accruing over a given period of time" , "Money received on which tax is payable" .)
