A federal agency contends hundreds of Thai workers hired by a contractor were mistreated

Federal authorities have filed a civil lawsuit accusing six Hawaii farms of "unlawful employment practices" in association with federally indicted farm labor contractor Global Horizons Manpower Inc.

Global Horizons' owner and employees are already facing several forced labor criminal charges in what's been called the most sweeping labor prosecution in U.S. history, but no farms were implicated in the crimes.

However, the U.S. Equal Employment Opportunity Commission alleges that supervisors from the six island farms and two others in Washington state were "engaged in, and more importantly knew of, or should have known that this was going on, and took no action to remedy it."

The Hawaii farms are Captain Cook Coffee Co., Del Monte Fresh Produce, Kauai Coffee Co. Inc., Kelena Farms Inc., Mac Farms of Hawaii LLC and Maui Pineapple Co. The lawsuits were filed Tuesday in Hawaii and Washington.
