One day, as she had done many times before, Diana was sitting in her car smoking on a break. This time, however, the owner of the business looked out the window and saw Diana smoking in her car. For some crazy reason, the employer thought Diana was smoking marijuana -- although there was no basis for this conclusion. He fired her the moment she returned from her break. What are Diana's rights? Is this legal at present? Is this fair in your opinion? Are there Constitutional issues here? Is it a breach of an employment contract?
