Crushed, and imposed our way of working (5,8)
I believe the answer is:
modus operandi
'way of working' is the definition.
'crushed and imposed our' is the wordplay.
'crushed' is an anagram indicator.
'and'+'imposed'+'our'='andimposedour'
'andimposedour' anagrammed gives 'MODUS OPERANDI'.
(Other definitions for modus operandi that I've seen before include "way of doing things" , "MO in full" , "Particular way of doing something (Latin)" , "this shows how it's done" , "Classically typical style" .)
