Morphology
The meaning 'an official card showing proof of membership in a labor union' is directly and compositionally derived from 'union' (workers' organization) + 'card' (a small ID/payment item); a B1 learner who knows both words can infer a card belonging to or issued by a union. This construction follows a common noun+noun compounding pattern found across languages (e.g., 'membership card', 'carnet sindical'), so the sense is transparent and predictable.
Etymology
Union card comes from labor groups giving each member a small card that proved they belonged to the union; picture a worker holding up the card to enter a meeting. So a 'union card' means the official proof that you are a member of the union.
