Describe a time when you felt you were being treated unfairly at work. What was the situation and how did you respond?

"I can't think of a lot of examples of this, but I do recall a time where my coworker and I were getting a lot of heat from our supervisor. We felt like we were constantly getting blamed for things that were beyond our control and were being treated unfairly because of it. It wasn't a big deal at first, but when it became an issue we both went and talked to him about it. In the end, we realized he was under a lot of pressure from his managers and was just passing along the annoyance to us. Once he realized how it was affecting us, he stopped and talked directly to his managers about the issues he was having."
