The Ethical Trading Inintiative

What is ethical trade?
Ethical trade means that retailers, brands and their suppliers take responsibility for improving the working conditions of the people who make the products they sell. Most of these workers are employed by supplier companies around the world, many of them based in poor countries where laws designed to protect workers' rights are inadequate or not enforced.

Companies with a commitment to ethical trade adopt a code of labour practice that they expect all their suppliers to work towards. Such codes address issues like wages, hours of work, health and safety and the right to join free trade unions.
