Amused with employment (3)

I believe the answer is:

use

'employment' is the definition.
(how something is used)

'amused with' is the wordplay.
'with' says the answer is hidden in the clue.
'USE' can be found hidden inside 'amused'.

(Other definitions for use that I've seen before include "Apply, employ" , "Exploit; custom" , "Resort to - operation" , "Employment; utilise" , "Manipulate" .)

I've seen this clue in The Mirror.
