The largest nurses strike in New York City history entered its second day on Tuesday.

Bronx nurses are once again forming picket lines outside major hospitals, including Montefiore Medical Center in Morris Park.

Nearly 15,000 nurses represented by the New York State Nurses Association walked off the job Monday after contract negotiations collapsed.

Nurses say they are demanding safer working conditions, protection from workplace violence, and improved staffing levels to better care for patients.

Picket lines stretched across private hospitals citywide, including the Mount Sinai Health System and NewYork-Presbyterian facilities.

Nurses could be seen chanting, ringing bells, and holding signs as they vowed to stay out until a fair deal is reached.

Montefiore disputes the union’s demands, telling News 12 that meeting them would cost the health system an estimated $3.6 billion, including a proposed 40% wage increase.

The hospital also raised concerns about what it called “troubling proposals,” including limits on terminating nurses found to be impaired by drugs or alcohol while on the job.

Mount Sinai officials said just under 20% of their nurses reported to work on the first day of the strike and expect similar staffing levels Tuesday.

Both hospital systems are spending millions of dollars to bring in temporary nurses to ensure patient care is not disrupted during the walkout.The strike is expected to continue as negotiations remain at a standstill.
