The latest National Labor Relations Board filing centers on the hospital’s 3BC medical intensive care unit. According to the union, management unilaterally altered work schedules for approximately 75 of the unit’s 100 nurses, forcing them to work every other weekend instead of their long-standing every-third-weekend rotation. Kelly Morgan, chair of the MNA bargaining committee, stated that many of these nurses had not been required to work such frequent weekend shifts in over a decade. She maintains there is no clinical or staffing justification for the shift, characterizing the move as direct intimidation following the July 8 walkout and subsequent four-day lockout.

This dispute adds further tension to upcoming contract negotiations scheduled for August 6. The MNA previously filed a charge on July 23 alleging the hospital illegally blocked neonatal intensive care unit nurses from joining the picket line. As bargaining resumes, the union continues to push for limits on temporary staffing and better retention incentives, accusing Mass General Brigham of prioritizing obstruction over addressing the core patient-care issues that triggered the initial labor action.
