Provoked to employ a staff all round (7)
I believe the answer is:
aroused
'provoked' is the definition.
('arouse' can be a synonym of 'provoke')
'employ a staff all round' is the wordplay.
'employ' becomes 'use' (synonyms).
'staff' becomes 'rod' (both can mean a pole or stick).
'all round' indicates putting letters inside.
'a'+'rod'='arod'
'use' inserted into 'arod' is 'AROUSED'.
'to' is the link.
(Other definitions for aroused that I've seen before include "Brought to" , "Woken - excited" , "Excited, stimulated" , "Inspired" , "Keenly excited" .)
