Administration at hospitals are currently in negotiations with unions over new ballot initiatives. The Service Employees International Union (SEIU) has proposed that insurance companies pay higher rates to hospitals with less funding. While SEIU representatives say they are open to alternative solutions, they have already collected 64,750 signatures for this ballot. The Massachusetts Hospital Association is one of the organizations that has opposed this ballot. Many of the SEIU members work in these hospitals that are considered "lower-paid" and would benefit it this ballot goes through.
