Employees across HHS began receiving notices of dismissal on Tuesday in an overhaul ultimately expected to lay off up to 10,000 people. The notices come 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. announced a plan last week to remake the department, which, through its agencies, is responsible for tracking health trends and disease outbreaks, conducting and funding medical research, and monitoring the safety of food and medicine, as well as for administering health insurance programs for nearly half of the country.
