Lied about not working (4)
I believe the answer is:
idle
'not working' is the definition.
(I've seen this before)
'lied about' is the wordplay.
'about' indicates anagramming the letters.
'lied' is an anagram of 'IDLE'.
(Other definitions for idle that I've seen before include "Ineffectual" , "no longer employed?" , "without basis" , "Do nothing, laze" , "jobless" .)
