LOL, imagine a socialist country where workers needed to organize to create adversarial relationships with other workers. Shake that liberalism from your brain. Unions are an organizational form against capitalists, a protorevolutionary form that wins through threat of harm to the state. No socialist country needs to have unions, because a socialist country is one in which the state is organized in accordance with the long-term interests of the workers as a class.
Cool, let them know that you know what's best for them and that they should organize themselves in a protorevolutionary formation and threaten to withhold their labor from society. You know best!
Your tankie brain knows that FOXCONN is a Taiwanese company, doesn't it? What's a filthy US-imperialist puppet company doing in the glorious socialist autonomous mainland provinces? Who is allowing them to exploit people there?
