Doctor interrupting faculty activity getting ban (7)
I believe the answer is:
embargo
'ban' is the definition.
(thesaurus)
'doctor interrupting faculty activity' is the wordplay.
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus).
'interrupting' means one lot of letters goes inside another.
'faculty' becomes 'ear' (ear is a kind of faculty).
'activity' becomes 'go' (go is a kind of activity).
'mb' placed into 'ear' is 'embar'.
'embar'+'go'='EMBARGO'
'getting' is the link.
(Other definitions for embargo that I've seen before include "Trade stoppage" , "Ban on commerce - mob rage (anag)" , "Order intended to prevent trade" , "Ban, veto" , "Trade barrier or publication ban" .)
