Employees across the massive U.S. Department of Health and Human Services have begun receiving notices of dismissal in a major overhaul expected to ultimately lay off up to 10,000 people. The notices came Tuesday just days after President Donald Trump moved to strip workers of their collective bargaining rights at HHS and other agencies throughout the government. Health Secretary Robert F. Kennedy Jr.’s announced a plan last week to remake HHS, which, through its agencies, is responsible for tracking health trends and disease outbreaks, conducting and funding medical research, monitoring the safety of food and medicine, and administering health insurance programs for nearly half of the country.
