Bob, retired from a large railroad company after 25 years, agreed to appear as an expert witness on the subject of railroad switches (his area of specialty). When he was called upon to testify, the attorney for the defendant asked him nothing about switches, but instead questioned him about his mental health. Years earlier, he had been hospitalized in a psychiatric ward and had been open in sharing that with his employer. It turns out that the employer had released this very sensitive information to the defendant's attorney, who used it to intimidate and discredit him. Afterwards, he called his former employer and asked to see his employment file. He was told it could not be found.
Bob's name has been changed to protect his privacy.
