Twenty years ago, there was Smith Barney’s Boom-Boom Room. Today, it’s Ellen Pao v Kleiner Perkins, the very high-profile sex discrimination trial that’s been going on for four weeks in San Francisco Superior Court.

Pao was a junior partner at Kleiner from 2005 to 2012, when she was fired. She says the firm discriminated against her, leaving her out of important meetings and passing her over for promotion while men moved ahead. Kleiner says she was a difficult employee who had a “female chip on the shoulder.” I wrote about it in my column today for TheStreet.com:

Among the affronts she has shared with the jury are the story of the female partner on a business trip who opened her hotel room door to see an uninvited Kleiner partner holding a bottle of wine and wearing his bathrobe; the co-ed business flight on a private jet where the conversation turned to porn stars; and the Kleiner meeting where a male partner approached a female partner to ask her to take notes. When the woman declined, he asked Pao to do it.

If Pao loses, it won’t bode well for women with grievances in the future. Women considering a lawsuit could wind up being warned “You know what happened to the woman in San Francisco,” said Linda Friedman, the Chicago lawyer who brought gender suits against brokerage firm Olde Discount Corp. in 1995, Smith Barney in 1996 and Merrill Lynch in 1997.
