Keep in mind that this ruling doesn't say it's a crime. It merely says, it's not covered by an exemption to the at-will employment rules that let a company fire you for any reason. If my boss doesn't like the fact that I put horseradish on my nachos, they can fire me for that. It's only exceptional cases where I'm protected from arbitrary and nasty and capricious actions. Also, put horseradish on your nachos, it's a good thing.
