Protect Workers In America!

Where are the laws to protect workers in America? I just learned if you are working for minimum wage and your employer doesn't like you they can just fire you?  We need more and stronger laws protecting hard workers! How can this be going on? You can't be fired for discrimination but anything and everything else is OK? No, this is not OK and the laws need to change to protect the people. If you agree please sign! There should have to be a valid reason in order for an employee to be fired.
