What did the court decide in Zipes v. Trans World Airlines, Inc.?
Answered for: US
filing a timely charge of discrimination with the EEOC is not a jurisdictional prerequisite to suit in federal court, but a requirement that, like a statute of limitations, is subject to waiver, estoppel, and equitable tolling
The Court held that missing the EEOC filing deadline does not automatically deprive a federal court of jurisdiction over a Title VII claim.
