> I would expect a government to have proper separation from church and state, so why is it weird to want a company to separate politics and mission

Because this is a non sequitur? You’re making appeals to protections enshrined in law to prevent the government from limiting the freedom and rights of individuals, when almost no such protections exist in the workplace. Why do people organize in their workplace? Because there exists no bill of rights for workers to prevent equivalent abuses of corporate power and hierarchy that are ostensibly so tyrannical when done by the government.

A better question would be why America has a two-track system of rights, where one must constantly defend their violation from the government, but also completely abandon them the moment they walk into their workplace.
