Excited or badly employed (6)
I believe the answer is:
roused
'excited' is the definition.
(rouse can mean to excite)
'or badly employed' is the wordplay.
'badly' indicates anagramming the letters (letters in the wrong order).
'employed' becomes 'used' ('use' can be a synonym of 'employ').
'or' anagrammed gives 'ro'.
'ro'+'used'='ROUSED'
(Other definitions for roused that I've seen before include "Woke or excited" , "Provoked" , "Woken up or angered" , "Made to waken or to become excited" , "Soured (anag.)" .)
