"How are they getting away with it?
On paper, seafarers have more international protection than many other workers through the International Labour Organisation and the International Maritime Organisation.
But ships are covered by the labour protection laws of the country in which theyre registered. So, many cruise ships fly the flag of places like Panama, Bahamas and Liberia that have weak laws and weak trade unions and are happy to turn a blind eye to international maritime standards. These are known as 'flags of convenience'.
For example, Disney has two cruise ships, 'Disney Magic' and 'Disney Wonder'. They both fly the Bahamas flag of convenience.
A galley assistant from Trinidad said: "In Disneys training they say it is one big family, you must give 100 per cent. But when you get on board, it's completely different. They don't give you 100 per cent. There's no chance to progress out of the galley, at least not on merit." Working hours are extremely long and workers say there is not even a system of recording overtime.
Disney says it will consider a union agreement if the majority of crewmembers want it. But Disney does not let union representatives on board and workers are scared to be seen with them in case they lose their jobs."
