University of Michigan Health has more than 7,500 nurses working without a contract. The agreement with the Michigan Professional Nurse Council (MPNC) expired March 31, 2026, and negotiations have been stalled since October 2025. That's roughly seven months without progress on a contract covering one of the largest academic medical center nursing workforces in the Midwest.
Two specific issues are now driving an unfair labor practice filing and community rallies. First: the hospital proposed staffing changes that would increase patient assignments in some units. Second: Michigan Medicine installed AI-driven workplace monitoring sensors without prior bargaining — something the union says violates their collective bargaining rights under the NLRA.
The AI Monitoring Issue
This is the more legally significant of the two disputes. Employers covered by the NLRA have an obligation to bargain in good faith over workplace changes that affect terms and conditions of employment. Installing surveillance or monitoring technology that tracks nurse activity, location, or patient care performance is exactly the kind of workplace change unions can demand to bargain over before implementation.
Michigan Medicine apparently didn't do that. The sensors went in, and the union learned about them after the fact. MPNC President Kara Ayotte told local media: "As we increase nursing workload and add more patients to your patient assignment, it becomes harder to provide that high quality complex care."
The ULP charge is a formal complaint to the National Labor Relations Board alleging the hospital violated its duty to bargain. ULP charges trigger an NLRB investigation. If the board finds merit, it can order bargaining, rescind the unilateral change, and in some cases award remedies. More immediately, a meritorious ULP finding strengthens the union's position in contract talks and can authorize an unfair labor practice strike, which carries stronger legal protections for striking nurses than an economic strike.
The Staffing Proposal
The proposed patient load increases affect high-acuity units. University of Michigan Health handles one of the most complex patient mixes in the state: Level I trauma, transplant, cardiac surgery, NICU, high-risk OB. Adding patients to those assignments isn't abstract. Nurses are describing it as a direct impact on the quality of care they can deliver on any given shift.
The contract stalemate comes at a moment when health systems are broadly using AI and "intelligent workload" tools to optimize staffing — which in practice often means finding where they can reduce resources per nurse without triggering formal safety violations. The UM Medicine situation is a textbook case of what that tension looks like in a major academic medical center.
Why This Matters Beyond Ann Arbor
The AI monitoring piece is the precedent that matters. As health systems roll out ambient AI, activity-tracking sensors, and workload optimization tools, how much input nurses have in their implementation will become a standard union bargaining issue. The UM Medicine ULP is an early significant test case for whether health systems must bargain over AI deployment before implementation, or only respond to union demands after the fact.
If you work at a system that has recently deployed AI monitoring tools without bargaining or staff consultation: document when it happened, what it tracks, and whether you were consulted. That record matters if your shop steward needs to build a case. The UM Medicine nurses are setting a road map that other unions will follow.
The Broader Michigan Context
The UM Medicine dispute sits alongside the ongoing Henry Ford Genesys strike — now past nine months — making Michigan one of the more active nursing labor markets in the country. These two disputes are different in specifics but connected by the same underlying dynamic: nurses pushing back against management decisions that affect patient safety and working conditions without adequate union consultation.
Michigan also just granted NPs full practice authority in 2025, adding another dimension to healthcare workforce politics in the state. The simultaneous gains in NP scope and ongoing battles over RN working conditions reflect a healthcare sector in transition — one where the rules are changing faster than contracts and institutional relationships can keep up with. For nurses watching from outside Michigan, these disputes are indicators of where the national labor landscape is heading: AI in the workplace, staffing optimization, and post-pandemic contract fights that still haven't fully resolved.
UM Medicine has not publicly set a timeline for resuming substantive negotiations. The NLRB ULP investigation process will proceed on its own schedule. In the interim, over 7,500 nurses are working under the terms of an expired contract.
