The first of this month marked May Day. Many only remember it as the day when the former Soviet Union rolled out a procession of tanks, missiles, and soldiers. But many Chicagoans also know the day’s historic significance has to do with labor. Most nations still celebrate the rights of workers on May Day. For our May Day commemoration we focus on migrant workers. We’ll have a discussion on the rights of migrant workers from across our southern border in an era of globalization. And much of the fish that ends up on your dinner plate once swam in the Gulf of Thailand. Thailand's seafood industry attracts thousands of illegal immigrants from neighboring Burma, seeking under-the-table jobs. But most consumers are unaware the seafood they eat could have been caught by a seafood slave. We'll hear a report.
