Excited area staff accepting employment (7)
I believe the answer is:
aroused
'excited' is the definition.
(arousing is a kind of exciting)
'area staff accepting employment' is the wordplay.
'area' becomes 'a' (maths abbreviation).
'staff' becomes 'rod' (I've seen this before).
'accepting' means one lot of letters goes inside another.
'employment' becomes 'use' ('use' can be a synonym of 'employment').
'rod' placed around 'use' is 'roused'.
'a'+'roused'='AROUSED'
(Other definitions for aroused that I've seen before include "Brought to" , "Keenly excited" , "Inspired" , "Excited, stimulated" , "Woken - excited" .)
