Yahoo's staff ratings killed moraleOne of the uglier parts of the process was a series of quarterly “calibration meetings,” in which managers would gather with their bosses and review all the employees under their supervision. In practice, the managers would use these meetings to conjure reasons that certain staff members should get negative reviews. Sometimes the reason would be political or superficial. Mayer herself attended calibration meetings where these kinds of arbitrary judgments occurred. The senior executives who reported to Mayer would join her in a meeting at Phish Food and hold up spreadsheets of names and ratings. During the revamping of Yahoo Mail, for instance, Kathy Savitt, the C.M.O., noted that Vivek Sharma was bothering her. “He just annoys me,” she said during the meeting. “I don’t want to be around him.” Sharma’s rating was reduced. Shortly after Yahoo Mail went live, he departed for Disney.
