Rejected job in remote settlement (7)
I believe the answer is:
outpost
'remote settlement' is the definition.
(I've seen this before)
'rejected job' is the wordplay.
'rejected' becomes 'out' (I've seen this in other clues).
'job' becomes 'post' (post is a kind of job).
'out'+'post'='OUTPOST'
'in' is the link.
(Other definitions for outpost that I've seen before include "Distant station or branch" , "settlement difficult to reach?" , "settlement far off" , "Small camp some distance away from the main army" , "isolated stronghold" .)
