Artist meeting politician, worker out of control? (7)
I believe the answer is:
rampant
'out of control?' is the definition.
(thesaurus)
'artist meeting politician worker' is the wordplay.
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'meeting' is a charade indicator (letters next to each other).
'politician' becomes 'mp'.
'worker' becomes 'ant' (worker is a type of ant).
'ra'+'mp'+'ant'='RAMPANT'
(Other definitions for rampant that I've seen before include "Fulminate" , "Unchecked - standing up on hind legs" , "Spreading unchecked" , "Out of control" , "Unbridled" .)
