Gave up work (7)
I believe the answer is:
retired
'gave up work' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for retired that I've seen before include "Gave up job, relaxed on pension" , "No longer active in work or profession" , "Gone to bed" , "claiming a pension?" , "Stopped work - went to bed" .)
