Many women at Amazon attribute its gender gap — unlike Facebook, Google or Walmart, it does not currently have a single woman on its top leadership team — to its competition-and-elimination system. Several former high-level female executives, and other women participating in a recent internal Amazon online discussion that was shared with The New York Times, said they believed that some of the leadership principles worked to their disadvantage. They said they could lose out in promotions because of intangible criteria like "earn trust" (principle No. 10) or the emphasis on disagreeing with colleagues. Being too forceful, they said, can be particularly hazardous for women in the workplace.
Motherhood can also be a liability. Michelle Williamson, a 41-year-old parent of three who helped build Amazon's restaurant supply business, said her boss, Shahrul Ladue, had told her that raising children would most likely prevent her from success at a higher level because of the long hours required. Mr. Ladue, who confirmed her account, said that Ms. Williamson had been directly competing with younger colleagues with fewer commitments, so he suggested she find a less demanding job at Amazon. (Both he and Ms. Williamson left the company.)
