WASHINGTON: U.S. President Donald Trump's administration expects hundreds of health department officials will lose civil service job protections, making them easier to fire, as it carries out a plan to revamp the federal workforce, according to an internal memo reviewed by Reuters. Supervisors at several agencies in the Department of Health and Human Services received the memo, which said positions on their teams may be reclassified in an initial wave and that additional waves would follow. The change means people in those roles could be fired at will.
