Pushy people get promotion (4)
I believe the answer is:
hype
'promotion' is the definition.
(hype is a kind of promotion)
'pushy people get' is the wordplay.
'get' indicates a hidden word (I've seen 'gets' mean this).
'HYPE' is hidden in the letters of 'pushy people'.
(Other definitions for hype that I've seen before include "Puffery" , "Build up" , "Blatant or sensational promotion" , "injection" , "racket" .)
