Getting up insurrection (6)
I believe the answer is:
rising
I believe this clue is a double definition.
'getting up' is the first definition.
('rise' can be a synonym of 'get up')
'insurrection' is the second definition.

(Other definitions for rising that I've seen before include "Hill" , "Ascension" , "working one's way up" , "Moving upwards" , "Upwardly mobile" .)
