The document discusses performance reviews for three employees - Sarah, Mark, and Dick. Sarah and Mark exceeded expectations in their work but were unfairly criticized for voicing opinions, making others look bad by excelling, and personal attributes like gender and interests. In contrast, Dick performed poorly by missing work frequently and being unproductive, but was still given a better review rating because of personal attributes like gender and social activities that were preferred by management. The document criticizes unfair biases in performance evaluations.
