Note how Paula handles Mr. Pak's injury, which is certainly very serious. Reprimanding him right off the bat shows that she absolutely doesn't care for his welfare, and her desire to not have anyone outside the factory find out that he got hurt means that she's certainly aware that the working conditions at the factory are unsafe and illegal—she just doesn't care. Again, the powerless status of Paula's workforce means that they're unable to push back at all on this ill treatment, as they're all replaceable fairly easily and cannot turn to legal recourse.
