Really?There is no constitutional right to free speech in ANY workplace...
A limited forum is a type of a designated public forum. Here, the government limits access to a designated public forum to certain classes or types of speech. In Good News Club v. Milford Central School, 533 U.S. 98 (2001), the Supreme Court held that in a “limited forum,” the government may discriminate against classes of speakers or types of speech. However, the government is still prohibited from engaging in viewpoint discrimination. For example, the government may limit access to public school meeting rooms by only allowing speakers conducting school-related activities. It may not, however, exclude speakers from a religious group simply because they intend to express religious views.
Nonpublic forums are forums for public speech that are neither traditional public forums nor designated public forums. According to the Supreme Court in Minnesota Voters Alliance v. Mansky, 585 U.S. __ (201, in a nonpublic forum, the Government may restrict contents of a speech, as long as the restriction is reasonable and the restriction does not discriminate based on speakers’ viewpoints. Examples of nonpublic forums include airport terminals, a public school’s internal mail system, and a polling place.
Finally, some public property is not a forum at all, and thus is not subject to this forum analysis. For example, public television broadcasters’ are not subject to forum analysis when they decide what shows to air.
