Martyn Boyers, Managing Director, Grimsby Fish docks, "The situation escalated last week, we had people coming down, protesting, we had people shouting, hurling abuse, calling them names, causing them all sorts of problems. We even had threats to sink the barge so we had to take these things seriously." But workers here have played down any nationalism, saying their dispute is with the bosses. The refinery has stressed the contract will not mean British redundancies but protesters say they still have a way to go.
