(1) Affected employees and the representatives of affected employees.

(2) The Delaware Department of Labor Division of Employment and Training, WARN Act Administrator.

(3) The Delaware Workforce Development Board established pursuant to the federal Workforce Innovation Opportunity Act (P.L. 113-128) for the locality in which the mass layoff, plant closing or relocation will occur.

(b) An employer required to give notice of any mass layoff, plant closing or relocation under this chapter shall include in its notice the elements required by the federal Worker Adjustment and Retraining Notification Act (29 U.S.C. § 2101 et seq.). Notice shall include the name, job title, home address, telephone number, and email address of each planned dislocated worker.

(c) Notwithstanding the requirements of subsection (a) of this section, an employer is not required to provide notice if a mass layoff, plant closing or relocation is necessitated by a physical calamity or an act of terrorism or war.

(d) The mailing of notice to an employee’s last known address by either first class or certified mail, the hand delivery of notice to an employee, or the inclusion of notice in an employee’s paycheck shall be considered acceptable methods for fulfillment of the employer’s obligation to give notice to each affected employee under this chapter.
