Go to bed and start drawing a pension (6)
I believe the answer is:
retire
I believe this is a double definition.
'go to bed' is the first definition.
(synonyms)
'start drawing a pension' is the second definition.
(I've seen this in another clue)
'and' is the link.
(Other definitions for retire that I've seen before include "retreat" , "end occupation" , "climb the stairs" , "Quit work, take pension" , "call it a day" .)
