Discharge male employees, having finally set remuneration (7)
I believe the answer is:
payment
'remuneration' is the definition.
(thesaurus)
'discharge male employees having finally set' is the wordplay.
'discharge' becomes 'pay'.
'male employees' becomes 'men'.
'having' means one lot of letters go next to another.
'finally' says to take the final letters.
The last letter of 'set' is 't'.
'pay'+'men'+'t'='PAYMENT'
(Other definitions for payment that I've seen before include "Recompense, reward" , "Sum given for something" , "Discharge of debt" , "Sum of money handed over" , "Handing over money" .)
