Some workers are forced onto Thai fishing boats by their families, others by unscrupulous employment brokers. Nearly half the workers make less than $160 a month in exchange for back-breaking labor. Some might not see any money at all.
And their employers get away with it, because Thailand - the world's No. 3 seafood exporter after China and Norway -either lacks comprehensive laws to protect poor migrants from exploitation or fails to enforce existing laws, such as those prohibiting the employment of children younger than 15 in fishing.
