Federal employees from the Department of Defense marched on Capitol Hill yesterday in protest of a proposed personnel regulation overhaul. American Federation of Government Employees President John Sweeney told the hundreds of rallying employees that the National Security Personnel System "will jeopardize public safety and national security by taking away employee protections that allow workers to speak freely when they see wrongdoing or mismanagement." The AFGE and other unions representing government employees are planning to file a lawsuit. The decision to implement similar changes at the Department of Homeland Security has already led to one lawsuit, saying that the changes undermine the constitutional right of due process. AFGE General Counsel Mark Roth said of the DHS changes in a press release that managers will have free reign to retaliate against employees who challenge management decisions.
