Cutter has a way of not working on this (4,5)
I believe the answer is:
sick leave
'not working on this' is the definition.
The definition suggests a singular noun which matches the answer.
'cutter has a way' is the wordplay.
'cutter' becomes 'sickle' (sickle is a kind of cutter).
'has' is a charade indicator (letters next to each other).
'a way' becomes 'ave' (abbreviation for avenue, a type of 'way').
'sickle'+'ave'='SICK-LEAVE'
'of' is the link.
Can you help me to learn more?
(Other definitions for sick leave that I've seen before include "benefit for those who are ill" , "recovery period" , "Ill time off work" , "Time for workers to become better" , "Time off work for illness" .)
