A study released in March 2026 by the CUNY School of Public Health and the Workers Justice Project documented widespread injuries and mental‑health problems among delivery couriers in New York City. The research surveyed 561 workers drawn from an estimated 70,000 delivery workers in the city.

The findings link the high rates of injury and mental‑health issues to the physical demands of the job and to deactivation practices that affect couriers. Delivery work in New York City relies on a large workforce, many of whom operate in hazardous conditions and experience job‑related stress.
