Let alone, getting some time off (5)
I believe the answer is:
leave
I believe this is a double definition.
'let alone' is the first definition.
(synonyms)
'some time off' is the second definition.
(leave is a kind of time off)
'getting' acts as a link.
(Other definitions for leave that I've seen before include "Depart, go" , "Depart - on authorised holidays?" , "Time off; go" , "Depart - on office holidays?" , "Permission - time off" .)
