Paper directed at recent union members (8)
I believe the answer is:
confetti
'paper' is the definition.
(confetti is a kind of paper)
'directed at recent union members' is the wordplay.
I cannot quite see how this works, but
'at' could be 'on' (location) and 'on' is located in the answer.
This explanation may well be incorrect...
(Other definitions for confetti that I've seen before include "It's targeted at newlyweds" , "Bits of paper scattered at festive occasions" , "Alternative to rice" , "Paper rained on newlyweds" , "To infect (anag)" .)
