The union that represents more than 400 of the nation’s immigration judges is raising allegations of unfair labor practices by the Department of Justice’s Executive Office of lmmigration Review (EOIR).

The National Association of lmmigration Judges, whose members fall under the EOIR’s purview, on Friday filed a pair of charges with the Federal Labor Relations Authority, the federal agency that oversees labor disputes between the federal government and its employees. The complaints center on a “white nationalist” blog post distributed in a morning email dispatch by the DOJ to immigration court employees and the EOIR’s failure to provide information the union says would be relevant to respond to the DOJ’s request to decertify the judges’ union.
