Suggest being part of strike, so people rise up (4)
I believe the answer is:
pose
'suggest' is the definition.
(thesaurus)
'part of strike so people rise up' is the wordplay.
'part of' indicates a hidden word.
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'esop' can be found hidden inside 'strike so people rise'.
'esop' back-to-front is 'POSE'.
'being' acts as a link.
(Other definitions for pose that I've seen before include "Pretend to be somebody else" , "position" , "Models do it for photographic or artistic purposes" , "Model - ask (question)" , "Present (problem), sit" .)
