* TNT says more cost savings needed
* Welcomes proposals on smaller packages
* Wants to resume discussions
AMSTERDAM, Oct 26 (Reuters) - Dutch logistics firm TNT said it disagreed with the findings of a study commissioned by postal unions on the savings it had to implement but welcomed proposals to slim down employment packages.
Plans by the country's largest postal firm to cut up to 11,000 jobs have strained relations with unions since they were announced more than two years ago.
Unions on Monday announced the results of a study carried out by research agency Ecorys that they commissioned after they rejected a draft accord by TNT on April that included wage cuts.
"Since the unions' last study two years ago, TNT Post's volumes have dropped by 8 percent and, since 2000, TNT Post has been faced with a cumulative volume loss, currently totalling 25 percent," said TNT's director of human resources Gerard Aben.
TNT said in a statement Ecorys's findings that the company can stay healthy with fewer savings were unrealistic, but welcomed its conclusions that far-reaching cost reductions, including less employment benefits, are essential.
It said it hoped to resume discussions with the unions as soon as possible. Some 23,000 staff work at TNT's mail unit.
TNT shares were up 1.3 percent at 18.93 euros at 1352 GMT, outperforming Amsterdam's blue chip index, which was flat. (Reporting by Greg Roumeliotis; Editing by David Holmes)
