If your employer sells all or part of its business, there are certain protections for all affected employees: If the sale by a covered employer results in a covered plant closing or mass layoff, the required parties must receive at least 60 days notice. The seller is responsible for providing notice of any covered plant closing or mass layoff which occurs up to and including the date/time of the sale. The buyer is responsible for providing notice of any covered plant closing or mass layoff which occurs after the date/time of the sale. No notice is required if the sale does not result in a covered plant closing or mass layoff. Employees of the seller (other than employees who have worked less than 6 months in the last 12 months or employees who work an average of less than 20 hours a week) on the date/time of the sale become, for purposes of the WARN Act, employees of the buyer immediately following the sale. This provision preserves the notice rights of the employees of a business that has been sold.
