The head of the Bronx-based construction coalition, United Hispanic Workers, was expected to be charged Monday after allegedly threatening contractors with violence if they didn’t hire his members at job sites, reports the New York Daily News.

Chief of the organization, David Rodriguez, and his field director, Daryll Jennings, allegedly strong-armed contractors to hire construction workers from their group, often threatening them with violence and labor unrest, the report says.

The United Hispanic Workers was formed in 1982 to advocate for helping members of minorities groups enter into “white dominated building trades.”
