The legislation is expected to face a vote as early as this fall.
Supporters of the bill argue it will close a loophole that allows Amazon to avoid responsibility for worker injuries and demanding labor conditions.
By mandating direct employment, the act would make it easier for delivery drivers to form unions, a move backed by the International Brotherhood of Teamsters.
Amazon, the nation’s second-largest private employer, has warned that the proposed change would undermine its low-cost logistics model, leading to more expensive and slower deliveries for customers.
If passed, the New York City legislation could serve as a regulatory template for other cities and states across the country.
The International Brotherhood of Teamsters has already signaled plans to promote similar bills elsewhere, following a related proposal introduced in Chicago last year.
The outcome of this bill will directly affect the business mechanisms of large-scale delivery firms and the legal protections afforded to thousands of workers within the city's urban infrastructure.
