At-will employment is a term used to describe the employment relationship in which an employer can terminate an employee at any time, for any reason, with or without notice. This type of employment is the default rule in the United States, unless there is a contract or union agreement that states otherwise.
There are several benefits to at-will employment for both employers and employees. For employers, at-will employment provides flexibility in managing their workforce. They can hire and fire employees quickly and easily, which can be important in fast-paced or changing business environments. For employees, at-will employment provides the freedom to leave their job at any time, without having to give notice or provide a reason.
