The Constitution does not always protect free$-$speech rights for what public employees say on the job. Which of the following is true?

When a citizen enters government service, the citizen need not accept certain limitations on his or her freedom.

Public employees may speak out on matters of public$-$concern and have First Amendment protection but not when they speak out in the course of their official duties.

As public employees speak out and receive First Amendment protection, there is an acceptable chilling of the speech of all potential whistleblowers.

None of the above.
