Retired? Put it in new resume (8)
I believe the answer is:
emeritus
'retired?' is the definition.
(synonyms)
'it in new resume' is the wordplay.
'in' means one lot of letters goes inside another.
'new' is an anagram indicator.
'resume' anagrammed gives 'emerus'.
'it' inserted into 'emerus' is 'EMERITUS'.
'put' acts as a link.
(Other definitions for emeritus that I've seen before include "Honourably retired but retaining title" , "Title of one honourably retired from duty" , "Keeping rank, retired" , "Designation of retired person" , "Honorary title" .)
