In two employment cases, one involving race and the other, age, the court took an expansive view of workers' rights and avoided the narrow, ideology-based decisions that marked its previous term.

The justices read parts of an 1860s civil rights act and the main anti-age bias law to include the right to sue over reprisals even though neither provision expressly prohibits retaliation.

Justice Stephen Breyer, writing for the court in a case involving a black employee at a Cracker Barrel restaurant who was fired, said that previous Supreme Court decisions and congressional action make clear that retaliation is covered.

The idea that a provision of the Civil Rights Act of 1866, known as section 1981, "encompasses retaliation claims is indeed well-embedded in the law," Breyer said in the 7-2 ruling.
