Nurses at two other area hospitals, Mount Sinai Hospital and Montefiore Bronx, are still due to strike after not reaching agreements.
The new tentative agreement at Morningside and West brings the anticipated number of nurses to strike down from 8,700 to about 7,125.
A Mount Sinai spokesperson told CNN on Saturday the hospital system is actively bargaining with the Mount Sinai Morningside and West campuses under separate union agreements.
Another six will be transferred Sunday from the NICUs at Mount Sinai Hospital and Mount Sinai West, the spokesperson said.
“In addition, we have transferred close to 100 patients from the affected hospitals – The Mount Sinai Hospital, Mount Sinai West and Mount Sinai Morningside – to unaffected hospitals within the Mount Sinai system and partner hospitals in NYC and we continue to safely discharge patients who were schedule to go home.” All elective surgeries have been postponed, the spokesperson said.
