Rush into job (6)
I believe the answer is:
career
This clue is a double definition.
'rush' is the first definition.
(thesaurus)
'job' is the second definition.
(thesaurus)
'into' acts as a link.
(Other definitions for career that I've seen before include "Progression through working life" , "Progress in occupation" , "Go at top speed through a working life?" , "Rush - occupation" , "Business course through life" .)
