Worker Adjustment and Retraining Act (WARN)

Learn about the Worker Adjustment and Retraining Notification process, including how and when to submit a WARN Report to the MassHire Department of Career Services' Rapid Response Team.

Introduction to WARN

In 1988, Congress enacted the Worker Adjustment and Retraining Notification Act, commonly known as WARN. It ensures workers have ample time to prepare for job transitions. This may include sharing information on new job opportunities or offering retraining before job loss.

Rapid Response services by the MassHire Department of Career Services (MDCS) starts upon notification to either the Commonwealth of Massachusetts or MDCS Rapid Response team about the impending layoffs. If layoffs or plant closings occur due to foreign trade, learn more about the Trade Adjustment Assistance (TAA) program for further information.

WARN for Employers

As an employer, it is your responsibility to notify MassHire Rapid Response, local government officials, and employees at least 60 days prior to the mass layoff or plant closing.

A timely WARN filing can prevent class-action lawsuits against the company. Early warning also benefits the business. It can shorten the time that employees are on UI. It therefore may lower the UI charges associated with the layoff or closing.

WARN Requirements

A WARN filing is required when:

  • Worksite closing affects 50 or more employees; or
  • Mass layoff affects at least 50 employees and one-third of the worksite's total workforce; or
  • 500 or more employees at a single site of employment; or
  • Anticipated separate employment losses within a 90-day period meet WARN criteria.
Submit a WARN 

WARN Exemptions

A WARN is not required when the layoff(s) affect employees with fewer than 6 months on the job are not counted in the 100 or more full-time employee threshold.
