The majority of states conduct employment under the regulation of 'at will.' This means that an employer may terminate an employee at any point as long as it is not on the basis of anything defined as wrongful termination by the federal government. There are only a few instances where a job termination notice is required by law. One is through the WARN act of 1989. It requires employers of 100 people or more to give 60 days warning before major layoffs or factory a factory closing. Some states have created 'mini' warn laws. These are less restrictive versions of the law for companies with fewer than 100 employees. Aside from warn acts, a notice for termination is only required if specifically stated by the employer.
