Approach shortened for Scrooge — one makes concessions (11)

I believe the answer is:

compromiser

'one makes concessions' is the definition.

'approach shortened for scrooge' is the wordplay.
'approach' becomes 'come' (e.g. as imperative).
'shortened' means to remove the last letter.
'for' becomes 'pro' (as in being 'pro' something).
'scrooge' becomes 'miser' (Dickens' Ebenezer Scrooge is a miser).
'come' with its last letter taken off is 'com'.
'com'+'pro'+'miser'='COMPROMISER'

(Another definition for compromiser that I've seen is " negotiator".)

I've seen this clue in The Times.
