Nurses at RWJ University Hospital in New Brunswick are striking for a fourth day - and still no resolution is in sight.

Hospital officials say they have spoken to United Steel Workers 4-200, the union representing RWJ nurses, to establish a meeting to continue negotiations. They say a meeting has not been set yet.

Nurses have been on strike since Friday morning with contract talks going back about four months. Hospital officials say they've presented fair contracts, making the nurses some of the highest paid in New Jersey. However, nurses say this is about more than just money, it’s about staffing concerns too.

The hospital has brought in outside nurses during the strike. The union says that's the staffing needed year-round.

The hospital remains open, fully operational, and completely staffed, according to hospital officials. They say staffing levels throughout the hospital have been "appropriately maintained across all units and all shifts when considering both patient volume and acuity."

“Our top priority is to our patients. We remain steadfast in our commitment to delivering the highest-quality care in the safest environment. We want to reassure our patients, their families, and our community that we continue to care for our patients without interruption,” a Robert Wood Johnson University Hospital spokesperson said in a statement.

Hospital officials say they are deeply disappointed that the union decided to take the “extreme action” of going on strike. They say, "no one benefits from a strike, least of all, our nurses."
