A union offer? (8)

I believe the answer is:

proposal

'a union offer?' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for proposal that I've seen before include "Plan, suggestion" , "Offer - suggestion" , "union offer?" , "Offer, of marriage say" , "Suggestion put forward for consideration" .)

I've seen this clue in The Globe and Mail.
