Traditionally, most employer-employee relationships have been "at will." That is, the employee serves at the will of the employer, who reserves the right to terminate the relationship at any time and for any reason. Modern law continues to follow "at will" policies. However, many new work relationships are entering into employment contracts. An employment contract is where the duties and responsibilities of the employee and the obligations of the employer are spelled out in detail. Once it is agreed upon, the contract is signed by both parties, and so are bound to its terms by law. An employment contract usually stipulates wages and benefits, appropriate reasons for dismissal, as well as confidentiality, severance, and non-competition clauses in case the contract is breached, or the employee leaves once the contract expires.
