Why is my boss forcing me to do review questions for a project I’ve been doing for 15 months now? I work for a big prime contractor in the US and my team will be reviewd by corporate and need to complete review questions. We get a percentage out of 100 and that is part of your performance review. My boss is making me do the review questions when I’ve been working on the project for 15 months and she has been on it for three and she expects me to “get 100% on it”. <br><br>What are review questions for? What should I do? I am so stressed out rn.
