The Temporary employees can file discrimination claims, but only certain types of discrimination claims. Some claims require a certain period of employment for the employee to bring the claim. In other words, they had to be with the employer for a certain period of time to be able to have rights under that. An example would be under the Family Medical Leave Act where it would require a certain hours of employment and certain duration of employment to be able to have rights under that particular statute. Many employees can bring discrimination claims simply as temporary employees. There is no time period that they had to be employed by the employer, particularly if there is discrimination based on for example race or age or ethnicity.
