Employment for Poles? (5)
I believe the answer is:
posts
'poles?' is the definition.
'employment for' is the wordplay.
'employment' becomes 'post' (post is a kind of employment).
'for' becomes 's' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'post'+'s'='POSTS'
Can you help me to learn more?
(Other definitions for posts that I've seen before include "a couple seen propping up the bar?" , "Is dispatching" , "Sends by mail" , "Stakes" , "Positions, for guards say" .)
