Out of work, one gets led astray (4)
I believe the answer is:
idle
'out of work' is the definition.
(thesaurus)
'one gets led astray' is the wordplay.
'one' becomes 'i' (Roman numeral).
'gets' is a charade indicator (letters next to each other).
'astray' indicates anagramming the letters.
'led' with letters rearranged gives 'dle'.
'i'+'dle'='IDLE'
(Other definitions for idle that I've seen before include "having no effect" , "Still" , "Not doing much" , "lndolent" , "Explosive stuff" .)
