When one of Deborah Mayer's elementary school students asked her on the eve of the Iraq war whether she would ever take part in a peace march, the veteran teacher recalls answering, "I honk for peace."

Soon afterward, Mayer lost her job and her home in Indiana. She was out of work for nearly three years. And when she complained to federal courts that her free-speech rights had been violated, the courts replied, essentially, that as a public school teacher she didn't have any.

As a federal appeals court in Chicago put it in January, a teacher's speech is "the commodity she sells to an employer in exchange for her salary." The Bloomington, Ind., school district had just as much right to fire Mayer, the court said, as it would have if she were a creationist who refused to teach evolution.

The ruling was legally significant. Eight months earlier, the U.S. Supreme Court had decided in a case involving the Los Angeles district attorney's office that government employees were not protected by the First Amendment when they faced discipline for speaking at work about controversies related to their jobs. The Chicago appeals court was the first to apply the same rationale to the classroom, an issue that the Supreme Court expressly left unresolved.

But legal analysts said the Mayer ruling was probably less important as a precedent than as a stark reminder that the law provides little protection for schoolteachers who express their beliefs.

As far as the courts are concerned, "public education is inherently a situation where the government is the speaker, and ... its employees are the mouthpieces of the government," said Vikram Amar, a professor at UC's Hastings College of the Law in San Francisco. Whatever academic freedom exists for college teachers is "much, much less" in public schools, he said...

...The Mayer ruling was disappointing but not surprising, said Michael Simpson, assistant general counsel of the National Education Association, the nation's largest teachers' union. For the last decade, he said, federal courts "have not been receptive to arguments that teachers, both K-12 and higher education, have free-speech rights in the classroom."...

..."Teachers bring their creativity, their energy, their skill in teaching the curriculum, but ... a teacher in K-12 is really not at liberty to design a curriculum," said Negrón, who filed arguments with the court in Mayer's case supporting the Bloomington school district. "That's the function of the school board."...

..."Teachers hire out their own speech and must provide the service for which employers are willing to pay," a three-judge panel of the Seventh U.S. Circuit Court of Appeals said Jan. 24. "The Constitution does not entitle teachers to present personal views to captive audiences against the instructions of elected officials."

Mayer, the court said, was told by her bosses that she could teach about the war "as long as she kept her opinions to herself." Like the Los Angeles district attorney's employee whose demotion led to the Supreme Court's 2006 ruling, the appellate panel said, Mayer had no constitutional right to say anything on the job that conflicted with her employer's policy...
