On May 1, 2026, 870 registered nurses at SSM Health's St. Mary's Hospital in Madison, Wisconsin, filed paperwork to form a union with SEIU Wisconsin — the largest private-sector labor organizing effort in the state in at least 25 years. The National Labor Relations Board set June 11 as the election date. That vote is two days away, and what has happened in the intervening six weeks has generated national attention.
Nurses at St. Mary's allege a sustained campaign of anti-union pressure by SSM Health management that includes suspension threats, forced removal of union pins during work hours, confiscation of union literature from federally protected break room spaces, and — most visibly — an HR representative who reportedly compared wearing a union pin to displaying symbols associated with white supremacist hate groups.
What Nurses Say Happened
The allegations, reported by the Capital Times and corroborated by multiple nurses speaking on record, center on events that began within days of the May 1 election filing:
- Nurses wearing SEIU Wisconsin badge holders were ordered to remove them by management, then threatened with immediate unpaid suspension if they refused to comply.
- Union informational fliers posted in break rooms — spaces the National Labor Relations Act explicitly protects for organizing activity — were systematically removed by staff who nurses say were directed by management.
- Nurses were told they could not discuss the union while on the clock, another potential NLRA violation.
- In the most widely reported incident, when nurse Kelsey Mueller questioned why she had to remove an SEIU pin, an HR representative allegedly told her that wearing a union pin was comparable to wearing a symbol associated with the Ku Klux Klan.
Nurse Breanna Rhinesmith, one of the nurses who spoke publicly about the suspension threat, told the Capital Times: "We were told 'You will be suspended without pay and sent home today until you agree to comply.'" Rhinesmith said the threat came shortly after she and colleagues arrived for their shift wearing union badge holders.
Nurse Kelsey Mueller, on the HR comparison: "The comparison of a hate group to our unionization was extremely, extremely hurtful."
SSM Health issued a statement saying the system "respects the right of its employees" to organize, but declined to address the specific allegations about suspension threats or the HR representative's comment. The NLRB, which oversees union elections, can investigate unfair labor practice charges — nurses and the union have indicated they are documenting incidents for that purpose.
Why Nurses Are Organizing: Staffing First
The primary motivation nurses cite for pursuing a union is not wages — it's staffing. St. Mary's is a 361-bed hospital serving Madison's west side with a significant surgical and orthopedic program. Nurses describe patient loads they consider unsafe for the acuity they're seeing, and say management has been unresponsive to formal staffing concerns raised through existing channels.
The organizing effort began more than a year before the May 1 filing, with nurses gathering signatures, holding meetings, and building a supermajority of support before going public. The scale — 870 nurses in a single facility — reflects a high degree of internal coordination and indicates the staffing grievance is broadly felt rather than concentrated in a few units.
The June 11 election result will be closely watched nationally. If nurses vote yes, SSM Health St. Mary's becomes the largest newly unionized hospital in Wisconsin and a potential template for other SSM facilities. If management's conduct during the campaign results in NLRB unfair labor practice charges, the timeline and remedies could extend well beyond the vote. Either way, this is the model other hospital systems will study for how — and how not — to handle a union organizing drive in 2026.
Context: Wisconsin's Complicated Labor Landscape
Wisconsin is not a right-to-work state for private-sector workers — the state's 2015 right-to-work law applies only to private employment and has been the subject of ongoing litigation. The NLRA governs private hospital organizing regardless of state labor law, which means the SSM Health nurses are operating under federal protections that Wisconsin's state law does not diminish.
UW Health, Wisconsin's academic public system, operates under different rules as a public employer and has successfully resisted union drives by arguing state law doesn't require it to bargain. The Wisconsin Supreme Court unanimously ruled in 2025 that UW Health need not recognize unions under Wisconsin state law. That ruling does not affect SSM Health, a private Catholic health system — the federal NLRA fully applies here, and the NLRB election result is binding.
For bedside nurses watching this nationally: union elections at large hospital systems are increasingly contested. The Madison case is notable for the scale of the alleged management response and the public nature of the specific incidents. If the NLRB finds the suspension threats and literature removal constitute unfair labor practices, SSM Health could face bargaining order remedies — an unusual but not unprecedented outcome where the NLRB bypasses a re-election and orders the employer to bargain based on demonstrated bad-faith conduct during the campaign.
