Negotiator gets the password wrong (4,7)
I believe the answer is:
shop steward
'negotiator' is the definition.
(shop steward is a kind of negotiator)
'the password wrong' is the wordplay.
'wrong' indicates anagramming the letters.
'the'+'password'='thepassword'
'thepassword' with letters rearranged gives 'SHOP-STEWARD'.
'gets' acts as a link.
(Other definitions for shop steward that I've seen before include "Trade union representative" , "One who's organizing hands" , "Workplace representative of unionised employees" , "Union official" , "Unionist" .)
