In National Railroad Passenger Corp. v. Morgan (2002) 536 U.S. 101, the United States Supreme Court held that each new discrete discriminatory adverse employment action is separately actionable when raised in a timely-filed complaint. The Morgan Court explained that a new timely-filed complaint would not revive time-barred claims, even when they were related to acts alleged in timely filed charges, because "each discrete discriminatory act starts a new clock for filing charges alleging that act." (Id. at p. 113.) For this reason, the Court held an employee could file charges to cover discrete acts occurring within a new limitations period because "each incident of discrimination and each retaliatory adverse employment decision constitutes a separate actionable 'unlawful employment practice.'" (Id. at p. 114.)
