Answer:
A. The Worker Adjustment and Retraining Notification ( WARN )
Step-by-step explanation:
The worker adjustment and retraining act notification is a US labour law that protects employees, requiring employers with 100 or more employees to give a 60 days advance notification of industry closure and/or mass layoffs of employees.
ManyEEs Inc. did not follow the 60 days notification before their mass layoff of 500 workers. They made the decision to downsize the 500 workers on Jan 1st 2018 and then laid them off only 5 days later on Jan 5 2018.
In doing so, ManyEEs violated the Worker adjustment and Retraining notification act.
