Final answer:
PICs must inform relevant parties, potentially including ASBP, 60 days in advance of plant closings or large layoffs if they work for an employer with more than 100 employees as mandated by the WARN Act.
Step-by-step explanation:
The question relates to the obligations of Principal-In-Charge (PICs) under the Worker Adjustment and Retraining Notification (WARN) Act. This Act requires employers with more than 100 employees to provide written notice 60 days in advance of plant closings or significant layoffs. Therefore, if a PIC's employer is planning such actions, the PIC must inform the appropriate parties, which could include unions, employees, and government entities such as the Advanced Studies of Business Practices (ASBP), if relevant. The notice helps ensure that employees have sufficient time to seek other employment or retraining opportunities and to adjust to the impending changes.
