Female calls about European charity's money raiser creating additional advantages (6,8)
I believe the answer is:
fringe benefits
'additional advantages' is the definition.
'female calls about european charity's money raiser' is the wordplay.
'female' becomes 'f' (abbreviation).
'calls' becomes 'rings' ('ring' can be a synonym of 'call'**).
'about' means one lot of letters goes inside another.
'european' becomes 'e' (abbreviation e.g. EU).
'charity's money raiser' becomes 'benefit'.
'e'+'benefit'='ebenefit'
'rings' going around 'ebenefit' is 'ringebenefits'.
'f'+'ringebenefits'='FRINGE BENEFITS'
'creating' acts as a link.
(Other definitions for fringe benefits that I've seen before include "Perks" , "offered to hairdressers, quite possibly?" .)
