Especially considering that most US states are at-will employment states. Unless there's overt discrimination, an employee can be fired with or without warning, for any or no reason. They can and will find ways around. I was a sub-contractor for a large firm that provided IT outsourcing services. After 18 months of praise and thinking I walked on water, I was unceremoniously terminated. The lame excuse... I wasn't a good representative of the company to the client. Which was just after they found out I'm gay. They stayed just this of the lawsuit line.
