Remember that everyone has strengths and weaknesses. No one is infallible. Your willingness to consider suggested improvements implies that you are a dedicated employee worth keeping. Listen thoughtfully. If the information you receive is a complete surprise to you, tell your manager that you would like some time to digest everything and request a time to meet again. Do a self-appraisal to think of reasons why your manager might perceive the identified weaknesses. Go to the second meeting prepared to calmly ask questions.
