The rights and remedies provided to employees by the Act and its regulations are in addition to, and not in lieu of, any other contractual or statutory rights and remedies of the employees, and are not intended to alter or affect such rights and remedies, except that the period of notification required by the Act shall run concurrently with any period of notification required by contract or any other statute. Nothing in this Part shall be read to abridge, mitigate, reduce, remove, or otherwise affect an employer's responsibility to comply with the notice requirements set forth in the federal Worker Adjustment and Retraining Notification Act and regulations promulgated thereunder.
