Immigrant workers recruited from South America and the Dominican Republic after Hurricane Katrina filed a lawsuit Wednesday against a prominent local hotelier, saying they’re being exploited even though they came to the United States under a legitimate guest worker program.

More than 80 workers from Peru, Bolivia and the Dominican Republic have joined the lawsuit filed in U.S. District Court against Decatur Hotels and its president and chief executive, F. Patrick Quinn III. The workers are employed in housekeeping, maintenance and other hotel support jobs.
