UPDATE 1-TNT keeps cuts goal after union snubs pay deal

* Union rejects labour accord that included wage cuts

* Firm warns of thousands of redundancies if no agreement

* TNT still plans annual savings of 395 mln eur until 2015

(Adds detail, spokesman's comment, background)

AMSTERDAM, April 23 (Reuters) - Dutch mail company TNT NV (TNT.AS) stuck to its annual cost savings targets and raised the prospect of thousands of forced redundancies after postal union members rejected a draft labour accord that included wage cuts.

The firm said on Thursday it would maintain its target of 395 million euros ($514 million) in annual cost savings until the end of 2015, to compensate for declines in mail volume.

TNT warned the restructuring could entail the loss of 11,000 staff over a period of one to three years if there was no agreement with unions. But it was open to talks on other options for achieving the savings target.

"We hope (unions) come up with realistic alternatives to contribute to the savings," a TNT spokesman said.

TNT said last month it had reached an in-principle agreement with several unions in a deal that would save the company 125 million euros a year, but postal services staff have since voted against the deal.
