SACRAMENTO — A former Yahoo Inc. editorial director has sued the company for gender discrimination, alleging that female executives manipulated an employee evaluation system to get rid of him.

In a suit filed Monday in U.S. District Court for the Northern District of California, Gregory Anderson seeks unspecified damages and a judicial declaration that the Sunnyvale-based search engine and media company used its quarterly performance reviews, or QPRs, to justify at-will terminations that were in reality “capricious, arbitrary and the product of bias.”
