Have you ever been fired from a job without proper cause?

I always believed in giving my best at any job I had. I took pride in what I could accomplish. I was working in a hospital medical records department. I gave it my best. My supervisor said one day, “are you going after my job”? She was a very insecure person, mainly due to the over use of diet pills, was my guess. She worked from 8 to 5, and I worked from 3 to 11. So I only saw her for 2 hours. But in that 2 hours I saw very strange behavior. She would go from agitated, and almost yelling at some of the employees, then leave the room for about 15 minutes, and come back a completely different person. I suspected she was using something. So nosey me went and looked in her top desk drawer. There it was, a couple of bottles of diet pills. I saw the doctors name and knew who he was. So miss buttinsky here informed the doctor one evening when he came in. He said, she told me she was giving them to her sister and her daughter. Well, anyway he stopped the prescripton for fear he would wind up in trouble. When she ran out, she wound up admitted to the hospital with abdominal pain of obscure origin.
When she returned to work, she was a mama bear with everybody. She fired one girl, then filed an insubordination on me. Which never happened. I was let go, without proper cause.
