Miami-Dade reaches tentative labor pacts with four more unions

Miami-Dade County said Friday it has reached tentative agreements with four unions, but reached an impasse on the contentious question of whether workers in those groups will have to contribute an additional 5 percent of their wages toward health-care costs. The county said the pacts cover the Transport Workers Union Local 291, which represents transit workers; the American Federation of State, County and Municipal Employees, Local 3292, which represents solid-waste employees; AFSCME Local 121, which covers water and sewer employees; and AFSCME Local 199, which represents employees across an array of departments
