More than 4,500 nurses and home care clinicians at Brigham and Women's Hospital and Mass General Brigham Home Care walked off the job at 7 a.m. on Wednesday, July 8, 2026 — the largest nurse strike in Massachusetts history and one of the largest single-system healthcare walkouts in the country by headcount.
The Massachusetts Nurses Association called the one-day strike after seven months of contract negotiations between the MNA and Mass General Brigham produced no agreement on wages. MGB's proposal included no across-the-board cost-of-living increases for nurses in the bargaining unit, relying instead on annual step increases that the MNA argued do not keep pace with inflation or market rates. MGB's position: the 5% annual step increases nurses receive already place Brigham nurses among the highest-paid in the state.
The dispute did not end at 6:59 a.m. on July 9 when the one-day strike was scheduled to conclude. MGB announced it would lock nurses out of the hospital for four additional days, extending the work stoppage through July 13.
What the Union Is Asking For
The MNA is seeking wage increases of 3% and 4% over an 18-month contract term, along with protection against rising healthcare costs. MGB asked nurses enrolled in the Harvard Pilgrim Health Plan — roughly half of the bargaining unit — to absorb an additional 2.5 percentage points of their monthly premium contribution. The union characterized the combined effect of zero raises plus increased premium costs as a net wage cut.
Staffing concerns are also embedded in the dispute. The MNA has argued that MGB's approach to staffing relies too heavily on per-diem and temporary agency staff at the expense of investing in permanent RN positions — a pattern the union contends is both a patient safety concern and a factor in long-term wage compression for staff nurses who carry the institutional knowledge.

MGB's Position and the Lockout Decision
Brigham and Women's Hospital remained open and fully operational during the strike, relying on contingency staffing arrangements assembled during the months of bargaining impasse. MGB's decision to impose a lockout through July 13 — rather than allowing nurses to return after the one-day strike — is unusual even in the context of contentious healthcare labor disputes. The lockout effectively transforms a one-day demonstration into a nearly week-long work stoppage.
MGB has not publicly characterized its lockout rationale beyond operational continuity planning. Unions and labor law observers generally note that lockouts following ULP-style strikes can create additional NLRB exposure if the original strike qualifies as an unfair labor practice strike rather than an economic strike — a distinction that affects nurses' right to immediate reinstatement. The MNA has not publicly characterized the July 8 action as a ULP strike in available statements.
Why This Strike Is Structurally Significant
Brigham and Women's is not a marginal employer. It is one of the top-funded research hospitals in the United States, part of Mass General Brigham — a system with reported annual revenue exceeding $20 billion. The nurses' union characterization of the dispute as "MGB billionaires refusing to negotiate" is deliberately framed to contrast hospital financial scale with the wages of frontline staff.
The broader context: Boston and Massachusetts have been a recurring flashpoint for nursing labor action since the 2022–2023 cycle of major system strikes. This walkout is the largest single-system nurse strike in Massachusetts history by headcount — larger than the 2022 Saint Vincent Hospital strike (700 nurses, 301 days) and the January 2026 New York City strike context by comparison.
Zero across-the-board increases is a negotiating position that would be difficult to defend to a nurse with 10 years of seniority who has already maxed their step scale. Step increases don't help the nurse at the top of the band — that nurse gets zero in MGB's proposal. That's where the strike energy comes from.
MGB Home Care Clinicians — Separate but Parallel
The walkout at MGB Home Care involves roughly 450 home care clinicians in a separate but parallel dispute. The home care strike is scheduled to run through July 15, two days beyond the hospital lockout's July 13 end date. Home care nursing is a chronic staffing shortage area nationally, and a weeklong work stoppage at one of New England's largest home care operations will have patient-discharge and continuity-of-care implications beyond the hospital setting.
What Comes Next
With the lockout set to expire July 13, the practical pressure to resume bargaining intensifies. Neither side has announced new negotiations scheduled as of this writing. The MNA has the option to authorize additional strike actions if the lockout is resolved without a contract. Travel nurses and agency staff sourced for contingency coverage during the work stoppage will factor into MGB's cost calculation — temporary staff costs typically run well above permanent staff wages, creating financial incentive for MGB to resolve the dispute.
The outcome of this strike will set a reference point for every major Massachusetts nursing contract negotiation in the 2026–2027 cycle. What MGB ultimately agrees to — and what it doesn't — will be read closely by nurses at MGH, Beth Israel Deaconess, Tufts Medical Center, and other Boston-area systems currently in or approaching contract bargaining.
