Many, many people misunderstand the 1st Amendment. It was never intended to protect your speech in the workplace. Your employer has every right to restrict your speech in the workplace in any and all respects. Your employer even has the right to restrict your speech in public.
What the 1st Amendment does is prohibit the United States government from restricting your speech. The 14th Amendment extends this prohibition to the States.
