If a private citizen breaks into someone’s house because she thinks there might be something of hers, no rights have been violated?

No. Your constitutional rights are those rights found in the Bill of Rights and later amendments. The "right" to life, liberty and the pursuit of happiness are flowery words found in the Constitution but basically do not amount to anything of substance or legal relevance.

No - not constitutional rights. In your scenario, statutory laws have been violated. Those laws exist to protect fundamental rights. But, again, we're talking about constitutional rights.
Me firing you for presenting an image counter to what I want my corporate image to be does not deprive you of life, liberty or the pursuit of happiness. It is ending a mutually voluntary relationship. Much like how you’re free to quit when I tell you what our corporate image is going to be.
