A union representing workers at Boston's Logan Airport is helping four former employees sue the Trump administration over job loss. The workers claim they lost their jobs because they are immigrants. All four worked as cabin cleaners and had "Customs access seals" which allowed them to enter U.S. Customs and Border Protection security areas within the airport. The Service Employees International Union (SEIU) alleges that the administration revoked their Customs seals due to "unacceptable risk" and part of a racist effort to purge immigrants from the workforce and scapegoat them for national problems. In total, 80 immigrant workers across the country are affected.
