May an employee assert a hostile work environment claim under the Age Discrimination in Employment Act (ADEA)? In Blumenshine v. Bloomington School District No. 87, the U.S. Court of Appeals for the Seventh Circuit responded affirmatively, and, in so doing, joined a number of its sister circuits that had previously recognized such a claim. This case serves as a significant reminder to employers to understand how age discrimination can manifest in the workplace and the legal standards required to prove such claims.
