A little over a year ago, three major employers—T-Mobile, Amazon, and Cox Communications—were sued for allegedly discriminating on the basis of age in the way they recruited new employees via Facebook. The plaintiffs’ lawyers targeted not only these three employers but also asserted claims against a “defendant class” of every employer that used age restrictions in their recruiting advertisements on Facebook. They also sent demand letters to scores of employers and filed charges of discrimination against yet more. Though the lawsuit and charge investigations are ongoing, the plaintiffs’ lawyers are now sending a new wave of demands to more employers and filing more charges of discrimination with the EEOC and state enforcement agencies. Employers who have not yet been targeted should take steps now to prepare.
