Subject to work experience (7)
I believe the answer is:
undergo
'experience' is the definition.
('undergo' can be a synonym of 'experience')
'subject to work' is the wordplay.
'subject to' becomes 'under' (I've seen this before).
'work' becomes 'go' ('go' can be a synonym of 'work'**).
'under'+'go'='UNDERGO'
(Other definitions for undergo that I've seen before include "Suffer, endure" , "Experience - bear" , "Suffer reverse" , "put up with" , "Endure for guerdon" .)
