U.S. Secretary of Labor Thomas Perez recently filed suit against Laborers International Union of North America Local 872 for disqualifying an “opposition” candidate for union office based on his failure to pass a literacy test and apparently his failure to establish proof of legal residency in the United States. The DOL says that the candidate, who is Latino, was required to read aloud a provision from the union’s constitution so that the election judges could determine whether he was literate. The judges then noted on his candidate questionnaire that he was disqualified because he was (allegedly) not literate and because he (allegedly) could not prove that he was legally in the United States. Then the union removed him from his position as shop steward, and then his employer fired him. Welcome to the Laborers’ union and its big tent.
