Well-organised isle ends reluctance to work (8)
I believe the answer is:
idleness
'reluctance to work' is the definition.
(I've seen this before)
'well-organised isle ends' is the wordplay.
'well organised' indicates an anagram.
'isle'+'ends'='isleends'
'isleends' is an anagram of 'IDLENESS'.
(Other definitions for idleness that I've seen before include "Lack of activity" , "pansy growers find love in?" , "State of inactivity" , "Reluctance to work" , "Inactivity, indolence" .)
