It can be hard to maintain a positive attitude when your boss questions your work. Although you may feel angry, upset or defensive, keep those feelings to yourself. Keep in mind that the purpose of the performance review is to help you become an even better employee. Your supervisor uses questions as tools to help you think about what you could have done differently in situations or what you can do better in the future. Answer questions truthfully, and take ownership of your part in any problems during the past year. You may feel less nervous about the review if you compile a list of questions you think your boss might ask.
