In New York state if you take a voluntary termination without cause package offered by your company do you qualify for unemployment benefits?

I'm not an attorney, but from the sounds of your question, the "package offered by your company" appears to be in lieu of unemployment benefits (chargeable to the company), in return for some type of remuneration payable to you. They could also be downsizing, etc. and to be fair to you, allow you to file, unchallenged, for unemployment. It would seem prudent to check with the unemployment office in regard to the agreement you have, to determine where you stand.
