Vietnamese here! It's expected for factory workers to OT a lot (12 hours a day / 6 days a week are normal occurrence, sometimes even full week). They are either forced by the companies/management or choose to OT themselves to make ends meet. I'm in a little bit better position myself but still very close to the people to see them struggling, especially minorities. It's definitely better than before but far from where it should be. I bet it's still better than life in shitholes like murica tho.
