In my experience unless you have someone higher-up actively advocating for you, this is often Cisco's legal way of pushing you out - the goals are usually vague enough that they can later say, u just didn’t meet expectations. Thanks for playing and now fu-k off.
If you genuinely believe it’s nonsense, start saving copies of anything that supports your performance such are emails, annual reviews, awards, praise from mgrs, anything showing you were doing well. once you’re let go, you will lose access to all of it, and things will become hard to find if you decde to challenge it legally. Also, if u end up using unemployment check whether your state offers a training or careerchange program near the end of your benefits. U usually only get to use it once so choose carefully. I used it as a stepping stone into a new career. Larned a lot at Cisco but it was an ugly divorce for me.
