I am posting this bc I am fascinated...how would YOU answer that question at your job when you have 4 years of (unsatisfactory) data. I really don't have a clue what a person could/should say in that situation. I know some of you will chime in with something unrealistic such as "I deserve to be fired" but if that is your response, I am guessing you have never truly fired someone for performance. Sometimes, in my experience, people will own it it you are firing them for cause (violation of policy,etc.). But never for performance. Have you had different experiences in your career?
