Nurses and Technicians at Delaware County Memorial Hospital in Upper Darby walked off the job at 6:45 am on Sunday launching a two-day strike. Pennsylvania Staff Nurses and Affiliated Professionals (PASNAP), the union representing striking nurses and technicians, say that the hospital’s new owners have failed to live up to promises they made to the community when they bought the hospital in July 2016. The new owners, Prospect Medical Holdings, Inc. Prospect is a for-profit, wholly-owned subsidiary of the private equity firm, Leonard Green & Partners, which also lists BJ’s, Shake Shack, and J. Crew in it’s portfolio. Prospect Medical Holdings has announced it will lock out striking nurses and technicians until at least Friday.
