Job termination occurs when a person is no longer employed at a company where he previously worked. Most employees are "at will," that is, they serve for as long as they or the employer wishes. That being the case, job termination usually occurs when one or both sides are not satisfied with a particular work arrangement, and are not able to reconcile their differences. At such point, the employee may seek employment elsewhere, and give appropriate notice when he has found a new job. Alternatively, the employer may seek to fire his employee if he is not satisfied with the work output. If the economy is hurting the company or if the company is restructuring, the employer may terminate several jobs by issuing layoffs. If the employee-employer relationship is based upon an employment contract, the job can only be terminated according to the guidelines set forth in that contract.
