NYC Nurses Strike Across Major Hospitals, Demand Safer Conditions. Thousands of nurses walked off the job at 10 major private hospitals across New York City on Monday, launching a massive strike over staffing shortages, healthcare benefits, and rising workplace violence from patients. The New York State Nurses Association says around 15,000 nurses are taking part. Newly elected Mayor Zohran Mamdani joined the picket lines, backing nurses who he says aren't asking for luxury paychecks, but basic protections, fair wages, and secure pensions. Hospitals argue the union's demands are costly. Mount Sinai estimates the proposals would add $1.6 billion over three years, with nursing costs jumping nearly 75%. Governor Kathy Hochul has declared a disaster emergency, allowing temporary nurses from outside the state and country to step in. Despite talks breaking down, hospitals say services remain open as negotiations remain stalled.
