Final answer:
The question pertains to the legal obligation of large employers to issue a written notice well in advance of plant closures or major layoffs, specifically 60 days ahead as a measure to protect employees.
Step-by-step explanation:
The query concerns the legal requirement for employers with over 100 employees to provide written notice at least 60 days prior to any plant closures or significant layoffs. This is a vital aspect of business law that deals with the rights of workers and the responsibilities of employers.
Federal regulations, like the Worker Adjustment and Retraining Notification (WARN) Act, mandate this notice period to protect employees from sudden unemployment without prior warning.
