For anyone who has been following the U.S. Supreme Court’s recent decisions interpreting wage & hour, discrimination and retaliation claims, yesterday’s decision in Kasten v. Saint-Gobain Performance Plastics (download here), can hardly come as a surprise.

Indeed, in a 6-2 decision, the Supreme Court concluded that to "file" a complaint, an employee need only provide

The United States Supreme Court today, in an 8-0 decision (Justice Kagan recused herself), ruled that Title VII retaliation provisions include protection to those people who have suffered an adverse employment action and are in the same "zone of interest" as another employee who filed a charge.  

What does that mean? Good question.
