A "stick up" job? (4)
I believe the answer is:
post
I believe this clue is a double definition.
'a stick up' is the first definition.
(as in posting a notice in public)
'job?' is the second definition.
(post is a kind of job)
(Other definitions for post that I've seen before include "Send; job" , "Publicly display; send" , "Contribute online" , "Upright - letters" , "Job; upright timber" .)
