CDC layoffs.

At least 600 employees of the Centers for Disease Control and Prevention are receiving permanent termination notices. The notes come in the wake of a recent court decision that protected some CDC employees from layoffs but not others. Many have been on administrative leave since the U.S. Health and Human Services Department sent layoff notices to thousands of employees at federal health agencies in April. But now, according to a union that represents CDC employees, at least 600 have been fired. The permanent cuts include about 100 people who worked in violence prevention.
