Paper worker rioted, surprisingly (6)
I believe the answer is:
editor
'paper worker' is the definition.
(I've seen this in another clue)
'rioted surprisingly' is the wordplay.
'surprisingly' indicates an anagram (a surprising ordering of the letters).
'rioted' anagrammed gives 'EDITOR'.
(Other definitions for editor that I've seen before include "Person responsible for publication;" , "Person who revises and prepares for publication" , "Reviewer of text" , "Head of a newspaper say" , "Newspaper boss" .)
