of the violation, up to 60 days. The liability may be reduced by the period of any notice that was given and any voluntary payments that the employer made to the employee, sometimes referred to as "pay in lieu of notice." U.S. district courts enforce WARN requirements. Workers, representatives of employees, and units of local government may bring individual or class action suits. Courts may allow reasonable attorney's fees as part of any final judgment. The U.S. Department of Labor is responsible to educate and inform employers and employees about WARN, and to provide assistance in understanding the regulations, but is not responsible for enforcing WARN. State and local laws In addition to the WARN Act, which is a federal law, several states have enacted similar acts that require advance notice or severance payments to employees facing job loss from a mass layoff or plant closing. For example, California requires advance notice for plant closings, layoffs, and relocations of 50 or more employees regardless of percentage of workforce, that is, without the federal "one-third" rule for mass layoffs of fewer than 500 employees. Also, the California law applies to employers with 75 or more employees, counting both full-time and part-time employees. The following states and localities have passed state or local WARN Acts. California Hawaii Illinois Iowa Maine Massachusetts Michigan (voluntary) Minnesota (voluntary) New Hampshire New Jersey New York Tennessee Wisconsin City of Philadelphia A number of states have laws that create ancillary duties at the time of job layoffs; but which generally do not seek to mandate advance notice or severance payments to workers in a manner similar to the federal WARN Act, other states' statutes, or the laws found in Canadian or European jurisdictions. Maryland, Missouri, Oklahoma, and Pennsylvania have statutes that require filing certain disclosure statements when businesses are the takeover targets of other corporations or when businesses are being dissolved. The statements generally require disclosure of plans to close facilities in the state. Connecticut requires employers to maintain health insurance for a certain period of time following the relocation of operations. Kansas requires the notification of state officials when businesses plan to close facilities or significantly cut production in select industries. Maryland, Michigan and Minnesota have statutes that ask employers to voluntarily provide advance notice to workers in the event of mass layoffs; however these states to not require compliance with the state's statute.
