'At-will' is a limited policy

Erick Becker in LA Labor Relations Examiner argues at-will employment clause involves only contracts of employment.

"While at-will language establishes a defense against a basic wrongful termination lawsuit, it doesn't provide a defense when an employee challenges a termination on other grounds, such as discrimination. In those cases, the employer must establish that there was some legitimate, non-discriminatory reason for termination – in other words, the employer is guilty until proven innocent".
