A union representing workers at six meatpacking plants has filed suit against immigration officials over raids that led to more than 1,000 arrests last year. The suit accuses the U.S. Immigration and Customs Enforcement of roughly handling more than 12,000 workers of the meatpacking company Swift. The United Food and Commercial Workers International Union says workers not accused of any crime were handcuffed for hours and denied access to phones, legal counsel, bathrooms and their families. The suit seeks financial damages and an end to the raids.
