Refer to the passage to answer the following question: "The boss's wife created a tense, competitive atmosphere between the workers. She would praise some people and downgrade others. Because of my experience, I can work faster than newer workers from China who are not as skillful. They would sacrifice their lunch and break time to catch up. I hated the way the boss made us compete. There were three of us in one department who had to produce 200 pieces. They would push us to see who could finish first. They were getting people to exploit themselves. How disgusting! I hate this!" In what ways did the boss's wife get workers in the factory to exploit themselves?
