Striker and manufacturer meet union organiser (10)
I believe the answer is:
matchmaker
'union organiser' is the definition.
(I've seen this before)
'striker and manufacturer' is the wordplay.
'striker' becomes 'match' (a match can be struck**).
'and' is a charade indicator (letters next to each other).
'manufacturer' becomes 'maker' ('maker' can be a synonym of 'manufacturer').
'match'+'maker'='MATCHMAKER'
'meet' is the link.
(Other definitions for matchmaker that I've seen before include "One seeking to bring couples together" , "One who arranges marriages for others" , "One brings together" , "Union organiser" , "Cupid" .)
