The Workers Adjustment and Retraining Notice (WARN) Act is a federal law designed to provide workers with additional time to find alternative jobs prior to (1) business closures, (2) mass layoffs, or (3) cumulative layoffs. The law applies to any private or non-profit employer with 100 or more full-time employees, and applies to both hourly and salaried employees, including those in management and leadership positions. However, this does not apply to (1) employees who have worked less than 6 months and (2) those who work less than 20 hours per week. Many states have their own versions of the WARN Act that supersede federal law. State versions are usually more liberal than the requirements of the federal version. For example, government versions may even apply to small businesses or also apply to part-time workers. Most labor practices liability (EPL) policies exclude coverage for claims for failure to file a notice under the requirements of the WARN Act, although most do cover defense costs associated with such charges. The basis for this exclusion is that such claims are under the control of the insured and therefore preventable.
