Issue of this writer securing little work after office's closure (6)
I believe the answer is:
emerge
'issue' is the definition.
(issue can mean to emerge or appear)
'this writer securing little work after office's closure' is the wordplay.
'this writer' becomes 'me' (the person who wrote the clues).
'securing' means one lot of letters goes inside another.
'little work' becomes 'erg' (erg is a scientific unit for work).
'after' says to put letters next to each other.
'closure' indicates one should take the final letters (the letter which closes the word).
The last letter of 'office' is 'e'.
'me' placed around 'erg' is 'merge'.
'merge' put after 'e' is 'EMERGE'.
'of' is the link.
(Other definitions for emerge that I've seen before include "Come out or surface" , "Come out or become known" , "Issue" , "Come forth or appear" , "Become known or apparent" .)
