Roused about employment (3)
'employment' is the definition.
'roused about' is the wordplay.
'about' says the answer is hidden in the clue (the clue goes around or about the answer).
'USE' is hidden within 'roused'.
(Other definitions for use that I've seen before include "Employ, put into service", "Employment; utilise", "Exploit unfairly", "Employ - advantage", "Employ or exploit".)
