This factory was unionized. That hardly seems like a sweatshop.
.
It still has third world wages and third world working conditions.
I'm pro-sweatshop. It's better than the manual farming jobs, famine, or prostitution that sweatshops help people to escape from. But I am consistenly in favor of sweatshops, regardless of their union or non-union status.
Perhaps the anti-sweatshop movement is really a front for the union organizers.
