Nurses at Crozer-Chester Medical Center warn that they may strike if no agreement is reached to replace their contract, which expires Wednesday.
The union representing the nurses has been negotiating with the hospital since March. In May, the 700-member union voted to authorize union leaders to give a 10-day strike notice, which has not been issued.
Nurses cite staffing as an issue, saying there are not enough of them to provide proper care.
A Crozer-Chester official told the Delaware County Daily Times the hospital spends more on nurse staffing than any comparable hospital in the region.
