Civil rights, including those in the First Amendment, are not absolute. Regarding speech, you also can't harass people, threaten them, defraud them, incite violence, distribute copyrighted information that isn't yours, interfere with others' activities (sing loudly in a movie theater), etc. Private entities such as your employer can restrict your speech in many ways.

I haven't seen these posts. Do you have an example handy?
