Under pressure from the internet, the recession and cheap competitors like Lidl and Aldi, Britain’s big supermarkets are desperate to woo customers back with special offers and price reductions. But who’s really paying the price? Channel 4 Dispatches investigates the supermarket supply chain and looks at some of the working lives of those at the very bottom: the people, who pick, pack and manufacture our food. With undercover filming, Morland Sanders lifts the lid on key supermarket suppliers. From field to factory, Dispatches examines hygiene, health and safety and the reality of life on minimum-wage, minimum-security, ultra-flexible contracts.
