Where: Warehouse and Shipbuilding Docks
You'll find three Sea Bees performing "barrel duty" near the Blue Casket. Talk to them and you'll primarily be speaking to Terry. Exhaust your topics with him to learn about the corruption in Rubacava and, if you've learned all you could from Velasco, about how to join the union and whether or not you could borrow their tools.
Other than talking to the bees for the story, this trophy is missable if you don't talk to them about the corruption and their role beneath it.
