Staff getting bug possibly creates controversy (7)
I believe the answer is:
polemic
'controversy' is the definition.
(polemic is a kind of controversy)
'staff getting bug possibly' is the wordplay.
'staff' becomes 'pole' (I've seen this before).
'getting' says to put letters next to each other.
'bug possibly' becomes 'mic' (microphone is a type of bug).
'pole'+'mic'='POLEMIC'
'creates' is the link.
(Other definitions for polemic that I've seen before include "Diatribe" , "Controversial line of argument" , "Controversy, argument" , "Controversial writing or oratory" , "debate" .)
