Washington (CNN) The union representing hundreds of US immigration judges is accusing the Justice Department of unfair labor practices.

The National Association of Immigration Judges outlined its claims in two filings submitted to the Federal Labor Relations Authority on Friday.

One filing centers around a link to a white nationalist blog post that was circulated in a daily briefing to employees of the department's Executive Office for Immigration Review in August.

"The intentional publication of this blog post has the effect of interfering with, restraining and coercing employees in the exercise of their rights," the union's petition says, noting that in addition to using anti-Semitic slurs to describe leaders of the judges' union, the blog post called for the union to be decertified.

Another filing from the union accuses the Executive Office of Immigration Review of failing to respond to a request for information during collective bargaining.
