Speaking out against recent actions by Miami-based Jackson Health System management, union president Martha Baker said she was deeply concerned that last week's 500-plus job cuts are long-term mistakes that will damage the quality of healthcare in South Florida. Baker, head of Local 1991 of the Service Employees International Union, said she also was refusing Jackson's request to renegotiate the contract changes that granted several pay concessions to help the struggling public system reduce a projected deficit of $230 million this fiscal year, the Miami Herald reports.
