Registered nurses at Rush University Medical Center in Chicago voted overwhelmingly to unionize on May 14–16, 2026. Of 1,830 eligible voters, 1,540 ballots were counted. The final tally: 1,190 in favor, 340 against — a 77% margin in favor of joining the National Nurses Organizing Committee (NNOC), an affiliate of National Nurses United (NNU), the country's largest RN union.
The vote covers approximately 2,000 registered nurses across Rush University Medical Center. The result was certified by the National Labor Relations Board and marks a major organizing win for NNU in the Midwest — and a significant shift in Chicago's academic medical center labor landscape. Rush is a 671-bed Level I trauma center and major teaching hospital on Chicago's Near West Side, affiliated with Rush University and Rush Oak Park Hospital.
What the nurses campaigned on
The organizing drive, which accelerated through early 2026, centered on three interconnected demands that will sound familiar to any bedside nurse: nurse-to-patient staffing ratios, wage improvements to close the gap with union peers at other Chicago academic medical centers, and stronger workplace safety protections after documented increases in patient violence incidents.
Rush nurses who spoke publicly during the campaign cited mandatory overtime, chronic short-staffing in overnight ICU and ER shifts, and a widening pay gap relative to University of Illinois Health and Northwestern Memorial — both of which have organized nursing workforces — as the primary drivers of the vote. Management spent an estimated $1.7 million on union-avoidance consultants during the organizing campaign, according to NNOC organizing filings, but the 77% margin suggests the messaging did not land.
What comes next
NNOC is now the certified bargaining representative for Rush RNs. Under NLRA rules, Rush University Medical Center and NNOC/NNU must bargain in good faith toward a first collective bargaining agreement. There is no statutory deadline, and first-contract negotiations at large hospital systems typically take 12–24 months — sometimes longer if management contests the scope of the bargaining unit or engages in delay tactics that generate unfair labor practice charges.
NNU has been effective at signing first contracts at similar-sized academic medical centers. The Chicago context matters here: the city has seen sustained healthcare labor activity through 2025–2026, and Rush's nurses will almost certainly benchmark their first contract against the most recent contracts at Northwestern, UIC, and the SEIU-organized Stroger Hospital. That benchmarking will set a floor for wage demands.
The broader 2026 organizing trend
Rush is not an isolated case. In 2026 alone, nurses at multiple major health systems have filed for NLRB elections or won organizing votes, continuing a wave that began accelerating after the 2022 Minnesota Nurses Association strike and the 2026 NYC hospital contracts. The NSI 2026 Workforce Report pegged RN turnover at 17.6% nationally with 158,600 positions vacant — data that nurses cite in organizing campaigns as evidence that management-set wages and conditions are not clearing the market.
For nurses at non-union hospitals watching from the outside, the Rush vote is notable for its margin. A 77% yes vote, achieved despite a seven-figure management counter-campaign, reflects a degree of workplace dissatisfaction that goes beyond wage comparisons. It is a data point worth tracking as hospital systems in the Midwest and Southeast face similar organizing pressure.
NNOC organizers have not confirmed which hospital systems they are targeting next in Chicago, but organizing activity in Illinois and Indiana has been elevated throughout 2025–2026.
What NNU first contracts typically deliver
Looking at recent NNU first contracts at comparable institutions gives a realistic sense of what Rush nurses can expect to fight for. At Stanford Health Care (2022), NNU nurses won 24% pay increases over four years and established enforceable staffing ratios. At Providence Oregon, the 2025 first contract delivered 20–42% cumulative raises over the contract life following a 46-day strike. First contracts at smaller systems have delivered more modest gains — typically 8–15% in the first contract year with additional increments over a 3–4 year term.
What matters more than the headline raise number is the contractual language around staffing. Nurses at Rush cite mandatory overtime and short staffing as primary grievances. A first contract that establishes minimum staffing floors and limits mandatory overtime protects nurses in ways that a wage increase alone does not. Whether NNOC prioritizes that language — and whether Rush management accepts it — is the real negotiating variable. Management will resist enforceable staffing floors more than almost any other contract term because they constrain scheduling flexibility and operational cost management.
Nurses at non-union Chicago hospitals watching this process should monitor how long first-contract negotiations take and what the final agreement covers. The timeline and outcome at Rush will be a data point in organizing conversations at other institutions in the market.
