For a week, I was an Amazon elf: a temporary worker who got a job through a Swansea employment agency – though it turned out I wasn't the only journalist who happened upon this idea. Last Monday, BBC's Panorama aired a programme that featured secret filming from inside the same warehouse. I wonder for a moment if we have committed the ultimate media absurdity and the show's undercover reporter, Adam Littler, has secretly filmed me while I was secretly interviewing him. He didn't, but it's not a coincidence that the heat is on the world's most successful online business. Because Amazon is the future of shopping; being an Amazon "associate" in an Amazon "fulfilment centre" – take that for doublespeak, Mr Orwell – is the future of work; and Amazon's payment of minimal tax in any jurisdiction is the future of global business. A future in which multinational corporations wield more power than governments.
