After a job? (4)
I believe the answer is:
post
I believe this clue is a double definition.
'after' is the first definition.
(prefix meaning after, eg post-war)
'a job?' is the second definition.
(post is a kind of job)
(Other definitions for post that I've seen before include "Maybe letters" , "Job - letters - stake in ground" , "Mail; office" , "Leave message online" , "Publish' mail' job" .)
