Not being able to discuss politics at work is not really the case for everyone though, it's worker politics that aren't allowed, if the politics agree with the owner class they'll set up a PAC for it. Whoever heard of an executive or board member fired for discussing politics that paint the organization in a positive light? I also think it's worth pointing out most companies would fire for this and are authoritative in structure and don't allow for democratic practices like elections, petitioning, protesting, etc. Just because it's that way now doesn't mean it always will be with good labor protections.
