I work for a company that does tv installs in people’s homes and this man that works a public job wouldn’t come out and talk to us but proceeded to belittle and berate his fiancé who was dealing with us. He kept yelling and dropping f bomb after f bomb and his fiancé was just a victim of it because all she could do was tell us in a calmer way what he was yelling. So instead of yelling or anything at him I left a google review of him. Not much later he went to managers assuming it was me that left the review. Can I be fired for it or is it a first amendment protected right?
