On August 24, 2026, nurses represented by the National Nurses United and its affiliates filed 10-day unfair labor practice strike notices at four Prime Healthcare facilities in three states. The coordinated one-day strikes are scheduled to begin September 3 at 7 a.m. local time and end September 4 at 6:59 a.m.
The four facilities involved:
- West Anaheim Medical Center (Anaheim, CA) — first contract bargaining, patient care and staffing disputes
- Saint Mary of Nazareth Hospital (Chicago, IL) — first contract bargaining, allegations of retaliation against union advocates
- Saint Mary's Regional Medical Center (Reno, NV) — ongoing contract dispute, prior June 2026 picketing action
- Shasta Regional Medical Center (Redding, CA) — contract negotiations, staffing and patient safety concerns
What the Nurses Are Demanding
Across all four facilities, nurses cite the same core issues: staffing ratios that compromise patient safety, management's refusal to commit to contract language protecting nurse advocates, and compensation structures that fail to reflect the scope of bedside work.
At Saint Mary of Nazareth in Chicago, nurses have alleged that Prime Healthcare has fired union organizers in retaliation for labor organizing activity — a charge filed as an unfair labor practice complaint with the NLRB. At West Anaheim Medical Center, nurses are bargaining their first contract and say management has refused to address basic patient-care protections in the proposed language.
"We are calling on Prime Healthcare management to come to the table with fair contracts that support patient safety and respect the rights of nurses to organize without fear of retaliation." — National Nurses United
Prime Healthcare's Track Record with Nurses
Prime Healthcare is a for-profit chain operating 45 hospitals across 14 states. The company has faced recurring labor disputes at multiple facilities since at least 2023, with nurses at several Prime hospitals citing understaffing, unsafe conditions, and what union representatives describe as an aggressive posture toward organizing activity.
In June 2026, nurses at Saint Mary's Regional in Reno picketed over stalled contract talks that had stretched to 11 months — with two union leaders alleged to have been fired during that period. Nurses at Chicago's Saint Mary of Nazareth staged a one-day ULP strike the same month after six organizers were allegedly terminated following a union election filing.
The September 3 coordinated action represents a step up in scale: simultaneous strikes across four facilities and three states, planned on the same calendar day, signal an intentional strategy by NNU to apply maximum visible pressure on Prime corporate leadership rather than isolating individual hospitals.
What Happens During a One-Day Strike?
Under California, Illinois, and Nevada law, hospitals must maintain patient care during nurse strikes. Prime Healthcare will likely bring in replacement nurses — agencies often fill these gaps, sometimes at rates exceeding $150/hour — to cover the walkout period. The cost to the hospital for a single day of replacement staffing at a medium-sized facility can run $500,000 or more.
One-day ULP strikes are a specific legal tactic: by framing the action as a response to unfair labor practices rather than a contract dispute, nurses can return to work after 24 hours without the employer having the right to permanently replace them. It keeps maximum pressure on management while protecting nurse jobs.
Why This Matters for Nurses
Coordinated multi-hospital strike notices are a significant tactical escalation. When nurses at four facilities in three states all serve notices on the same day for strikes on the same day, that's not coincidence — that's a union sending a message to corporate leadership that facility-by-facility containment isn't going to work anymore.
For nurses at non-unionized Prime Healthcare facilities — and for any nurse considering a travel contract at a Prime hospital — this is worth watching. A pattern of labor disputes at this scale tells you something about the organizational culture. Look up which agency filled the last strike. Understand what that contract actually covers. Know your rights.
And if you're at one of these four hospitals: the decision to strike or not is yours. But the 10-day notice means September 3 is set. Make sure you're talking to your charge nurse and union rep before then.
What Comes Next
Prime Healthcare has not publicly responded to the multi-state strike notice as of the publication of this article. The September 3 strikes will proceed unless Prime reaches tentative agreements with nurse bargaining units at each facility before the deadline.
NNU has indicated it will increase picket activity at other Prime facilities if the company does not address nurses' core demands before September 3. Watch for updates from NNU, CNA, and local TV stations in each city.
