Boycotts are big at the moment. On a global scale, many countries are boycotting Russia following its invasion of Ukraine. There are campaigns to boycott products produced in Turkey, Israel or China. Sporting boycotts are used by countries across the world to express their displeasure with their international rivals. And there are plenty of boycotts going on against companies, over working practices, supply chains and political stances. But international boycotts can be easily circumvented, and we can choose alternative products if we don't like a particular manufacturer. So is this low risk activism, or is it an effective way for ordinary people to hold businesses and nations to account? Do boycotts ever lead to permanent change? Above all, do they work?
