The Jackson Health System and its unions announced Tuesday a wide-ranging agreement that settled the hotly contested issue of emergency room staffing and resolved class-action grievances and a federal lawsuit sparked by the layoffs last spring. "This was a true negotiation of all our outstanding issues," said Martha Baker, president of SEIU Local 1991, which represents Jackson's nurses and other healthcare professionals. "It's truly a win-win." Chief Executive Carlos Migoya said in a prepared statement that the decisions were "difficult" but "in the transformation of Jackson we always analyze all of our business assumptions and latest data as we look for new opportunities to provide high quality healthcare at lower costs."
