I checked on internet and very many companies. Saw this-
Here at Zippia we have developed a database of over 250,000 companies that spans the entire country.
For this report, we looked at the companies headquartered in New York with at least 100 employees. That left us with 3,000 companies.
We then ranked each company from most to least current employees to determine the biggest companies in New York.
As it turns out, Duane Reade Holdings, Inc. looks to the be the biggest company in New York clocking in with 415,000 employees.
Duane Reade is owned by Walgreens who are in Illinois
