Under collective bargaining agreements approved Tuesday for 460 Clark County employees, wages will be frozen for two years. And, for the first time, full-time county employees will pay a portion of their health care premiums starting in January 2012.Francine Reis, the county’s human resources director, said negotiations are ongoing with unions that represent other county employees. The agreements unanimously approved Tuesday by Clark County commissioners were with Office and Professional Employees International Union Local 11, International Federation of Professional and Technical Engineers Local 17 and Laborers International Union of North America Local 335.The unions represent engineers, appraisers, office staff and other employees, and the agreements were worked out over 16 months, Reis said. The previous contracts had expired in June 2009, so the wage freeze applies to 2010 and 2011.In 2012, the employees will receive a 2 percent raise. They had been receiving, on average, a 3 percent raise every year.Responding to criticism from residents who testified that public employees get a much sweeter deal than private-sector employees, Commissioner Tom Mielke said it all averages out. “Our CEO makes a fraction of what the CEO of G.E. makes, while our truck drivers might make a little more,” Mielke said. County Administrator Bill Barron earns $170,000 a year. His salary, along with the wages of 280 management employees, has been frozen for two years.To Mielke’s point, the CEO of General Electric has a base salary of $3.3 million and total compensation package of $9.8 million in 2009, according to Forbes magazine.
