Despite what some managers think, they can not write you up if you are meeting your PA goals. I have been with the company for a very longtime and have seen some managers invent their "own" goals that are either not on the PA or try to write reps up for not exceeding the PA goals said manager wants. In each case the reps that this happened to went to HR and the managers got fired for it. Not every manager is like this and dont let these micromanaging bully managers get away with this. If you have a manager that tries to pull this go to HR.
