The company's Spanish subsidiary, Coca-Cola Iberian Partners, plans to shutter its plants in the northwestern Asturias region, the Balearic Islands, near Madrid and in southeastern Alicante, the union said in a statement.
UGT said it was seeking to negotiate with Coca-Cola to head off the closures, and would launch strikes and demonstrations to press its position.
The company, in a statement published in Spanish media, said it would try to place 500 of the affected workers in other positions, and offer the rest early retirement or attractive termination packages.
Coca-Cola Iberian Partners, which currently has 4,000 employees on its books, was founded last year by merging the seven bottling companies in Spain owned by the US brand.
