CHENNAI: Indian police on Tuesday said it has detained around 600 Samsung Electronics workers and union members for organising a street protest, as a strike at the South Korean firm’s home appliances plant in Tamil Nadu state entered its fourth week. More than 1,000 workers have disrupted operations and protested in a makeshift tent close to the factory near the city of Chennai since Sept 9. They have demanded higher wages and union recognition at the plant, which accounts for roughly a third of Samsung’s annual Indian revenue of $12 billion.
