Left work (6)
I believe the answer is:
labour
I believe this clue is a double definition.
'left' is the first definition.
(I've seen this before)
'work' is the second definition.
(I know that work can be written as labour)
(Other definitions for labour that I've seen before include "women have expected for months to be in" , "Left - work" , "Workers" , "See 1" , "Hard physical work" .)
