There is an old saying that claims that age is just a number. In the workplace, that same idea should hold true, but in many cases it doesn't. Some California employers may feel that, because one of their workers is no longer considered young, he or she may not be able to keep up, especially in a technological industry. Employees who believe they have lost their jobs because of their age may file an age discrimination claim in order to be returned to their position.
One of Twitter's former managers has a complaint against the company for age discrimination. The 57-year-old claims that, even after he received good performance reviews, which stated that he met the company's expectations, he still lost his job. He also claims that his supervisor made at least one criticizing mark about his age. He believes that, after he was removed from his position, he was replaced with workers who were much younger.
