My advice is never give up an opportunity to talk to your supervisor. But, I understand your apprehension about the traditional formal review process that happens once a year. I am opposed to the annual review process that most organizations use. The notion of taking notes on someone's performance over an entire year and then springing an evaluation on them over lunch is just silly. Not only are employees offended by this tactic, a year can be a lifetime in today's business environment.
Effective feedback is constructive and timely.
Annual reviews were effective when employees did one task, did it all year, and did it every year. Today, jobs change all the time. Employee are involved in all aspects of delivering a product or service to the customer. You need constant feedback, coaching, and mentoring. So instead of avoiding the meeting, I suggest that you go to the meeting and propose some changes.
