Young whippersnappers have heard the words, "free speech," so much that they think they are entitled to say anything, anywhere, anytime, to anyone. It just isn't so. Nor should it be.
Even jurisdictions with the broadest of policies regarding freedom of expression make it clear that the "right" comes with exceptions and responsibilities. Consider libel, copyright infringement, questions of national security, and so forth.
Shoot, consider telling your boss to take his design requirements, roll them up into a pointy object, and insert them where the sun don't shine. Hello unemployment line. And perfectly legally unemployed you are.
