Nathan Mayberg reports in the Register Star the Columbia County Board of Supervisors learned Mon., July 29, the county's health insurance obligations to its employees and retirees could rise to $100 million by 2020. The county's current obligation is estimated to be $57 million for a lifetime of health insurance to cover employees after they retire from employment. The figures are based on projections of the cost of health insurance, the size of the county’s workforce and longer life expectancy. After 10 years of service, county employees are eligible for county health insurance following retirement. With 10 years of service, the county pays half of a retiree's health insurance costs. For those with 25 years or more of service, the county covers 75 percent of their health insurance costs. Read the full story in the Register Star.
