I recently received a poor annual evaluation. During this period I was on FMLA for 4 1/2 months receiving treatment for breast cancer-then brain cancer. My employer was helpful at the time sending me smaller projects and 'busy" work,all which I completed as I recovered. When my evaluation arrived, I was shocked to learn that my performance was below standards and my production was lacking. I was place on a 90 day PIP and was told that this is just the company guidlines. In my seven years with the company I have always excellent evals. I don't want this to scar my excellent record. Any recommendations?
