Present work reduced for dissident (7)
I believe the answer is:
heretic
'for dissident' is the definition.
(I've seen this in another clue)
'present work reduced' is the wordplay.
'present' becomes 'here' (both can mean in attendance).
'work reduced' becomes 'tic' (I can't justify this - if you can you should believe this answer much more).
'here'+'tic'='HERETIC'
Can you help me to learn more?
(Other definitions for heretic that I've seen before include "One whose opinions are contrary to accepted religious beliefs" , "person with the wrong outlook" , "enough for victim of Inquisition?" , "Misbeliever" , "One who holds opinions contrary to accepted religious beliefs" .)
