Jobless (4)
I believe the answer is:
idle
'jobless' is the definition.
(I know that jobless can be written as idle)
This is the entire clue.
(Other definitions for idle that I've seen before include "Not in action or at work" , "Ineffectual" , "Not in active use" , "Fruitless" , "Monty Python's Eric, b. 1943" .)
