Indonesian fishers working out of Taiwan's Donggang harbor are pushing seafood buyers for better pay and treatment, a fight that pits low-wage workers against one of the world's big fishing industries.

• A new "Freedom for Fishers" campaign is demanding fair wages, real contracts, and Wi-Fi on every boat.
• Workers also want the right to form a union without being punished for it, plus a complaint system that actually works.
• Taiwan says it has fixed these problems, but the US Labor Department still lists Taiwanese seafood as made with forced labor.
• One fisher who reported being beaten at sea was fired and sent home once his employer found out about the complaint, the union says.
• Basic facilities are thin: two bathroom blocks on shore serve roughly 4,500 fishers in the area.

Outlook: The union wants a binding deal with the big seafood brands, so pressure now shifts to buyers at the top of the supply chain.
