discrimination at work due to manager's friendships with other employees and grudges the managers may have

I work in the radiology dept of a hospital. The director, manager, and my immediate supervisor are friends outside of work as well as with several employees and the favoritism is obvious. Me and several others have been accused falsly of poor pt care, destruction of property of the favorite's possessions (conjecture on their part) our jobs threatened, treated unfairly, etc in what we believe to be an attempt to make us quit, and one person retire early, so they can hire new grads cheaper and hire the young pretty technologists they get along with. This is an abbreviated summation but do we have any case at all? - Is this your question? Add additional information
