Italian union facing examination (6)
I believe the answer is:
tuscan
'italian' is the definition.
(I know that Tuscan is a type of italian)
'union facing examination' is the wordplay.
'union' becomes 'tu' (abbreviation for trade union).
'facing' is a charade indicator (letters next to each other).
'examination' becomes 'scan' (scan is a kind of examination).
'tu'+'scan'='TUSCAN'
(Other definitions for tuscan that I've seen before include "Person from Siena" , "Relating to a region of Italy" , "Italian dialect spoken in Florence" , "Classical architecture" , "Standard Italian" .)
