United States Labor Law - Job Security

Job Security

While most state and federal laws start from the presumption that workers who are not covered by a collective bargaining agreement or an individual employment agreement are "at will" employees who can be fired without notice and for no stated reason, state and federal laws prohibiting discrimination or protecting the right to organize or engage in whistleblowing activities modify that rule by providing that discharge or other forms of discrimination are illegal if undertaken on grounds specifically prohibited by law. In addition, a number of states have modified the general rule that employment is at will by holding that employees may, under that state's common law, have implied contract rights to fair treatment by their employers. US private-sector employees thus do not have the indefinite contracts (similar to US academic tenure) traditionally common in many European countries, Canada and New Zealand.

Public employees in both federal and state government are also typically covered by civil service systems that protect them from unjust discharge. Public employees who have enough rights against unjustified discharge by their employers may also acquire a property right in their jobs, which entitles them in turn to additional protections under the due process clause of the Fourteenth Amendment to the United States Constitution.

The Worker Adjustment and Retraining Notification Act, better known by its acronym as the WARN Act, requires private sector employers to give sixty days' notice of large-scale layoffs and plant closures; it allows a number of exceptions for unforeseen emergencies and other cases. Several states have adopted more stringent requirements of their own.
