Employers have ways around the WARN notice. They can send one out after the fact if they meet one of the “exceptions” or they don’t have to even send one depending on how many are laid off at once.

WARN Act requires employers to give notice of any mass layoff, that does not result from a plant closing but will result in an employment loss of 500 or more employees during any 30-day period. The Act also covers employment loss for 50-499 employees if they make up at least 33 percent of the employer's active workforce.
