Ahead of the Labor Day weekend, President Trump signed an executive order Thursday stripping union protections from federal employees. Under the order, several government agencies, including NASA, the National Weather Service and the Office of the Commissioner for Patents, will end their collective bargaining agreements with unions. Trump cast his executive order as critical for protecting national security. On Thursday, members of 30 unions and organizations marched in Washington, D.C., to protest Trump’s anti-worker policies.
