Change in deli not working (4)
I believe the answer is:
idle
'not working' is the definition.
(idle means doing no work)
'change in deli' is the wordplay.
'change in' indicates anagramming the letters.
'deli' is an anagram of 'IDLE'.
(Other definitions for idle that I've seen before include "Disliking work" , "-- Jack, pantomime character" , "Not occupied" , "Run out of gear" , "having no effect" .)
