The American Civil Liberties Union (ACLU) has accused Facebook of assisting employers in targeting job advertising to only certain classes of people. In this case, women were allegedly completely excluded from being able to see job ads from employers that intentionally chose to block women by using tools crafted by Facebook. The complaint was filed with the Equal Employment Opportunity Commission (EEOC) by an ACLU labor union. Lawyers say this is in violation of the Title VII of the Civil Rights Act of 1964 which made discrimination based on the sex of the applicant illegal. This lawsuit is eerily similar to the HUD complaint against Facebook when it allegedly allowed home owners to discriminate against certain classes of people by using Facebook tools to block viewing of housing ads based on the recipient's race, color, religion, sex, familial status, national origin, disability, and/or zip code. "The discrimination is always lurking below the surface," Romer-Friedman said. "Here we have evidence that employers never really abandoned the practice but because of their own stupidity and Facebook's transparency in the job ads, we know now this is a systemic problem." Facebook also excluded women from its own company, the complaint charged. It said Facebook uses its "Lookalike Feature," which searches for demographic similarities in customer bases, "in its own recruiting for positions at Facebook" which results in "discrimination against women in Facebook's own recruiting and hiring."
