Job cut not entirely doing for researcher (7)
I believe the answer is:
postdoc
'researcher' is the definition.
(someone doing postdoctoral research)
'job cut not entirely' is the wordplay.
'job' becomes 'post' (post is a kind of job).
'cut' becomes 'dock' (docking is a kind of cutting).
'not entirely' means to remove the last letter.
'dock' with its final letter taken off is 'doc'.
'post'+'doc'='POSTDOC'
'doing for' is the link.
(Other definitions for postdoc that I've seen before include "Researcher" , "Someone doing advanced research" .)
