San Francisco: A Facebook engineering manager who quit her job this month has alleged harassment at the workplace after she criticised the social media giant for lack of diversity. Sophie Alpert who headed a key open-source project called React at Facebook, tweeted on January 11: “Today’s my last day at Facebook.” In an internal post seen by CNBC, she revealed the reason behind her decision, alleging she was harassed by colleagues after criticising the lack of diversity at the company. “Facebook is good for many people, but it’s not the right place for me right now,” Alpert wrote on Workplace by Facebook which is an internal enterprise connectivity platform. “I want to spend my time at a place willing to push further on diversity and inclusion. One where it’s not OK to write on Workplace that white privilege doesn’t exist,” she said.
