Grading depends on whether you want to ask yourself or what others think. Ask yourself salary, ask others position. Is it necessary to make this so clear? You say that people are team leaders and you are team members. Even if you are the same informant, you are not equal. I think your working group has a leader, and you and he are the same target. I don't think you agree with this rating. Your working group has a leader. You may have to ask the team leader when you need to report.
