What Are At-Will Employment States Image

For almost anyone who’s had a job or employed people, the two-week notice is a familiar concept. But did you know it’s often more of a custom(opens in a new tab) than a requirement? Enter at-will employment.

At-will employment is a common practice in the United States, but what exactly does it mean? And which states follow this employment model? Here, we’ll explore the idea of at-will employment and the state laws that govern it.

What is At-will employment?

At-will employment means an employer can terminate an employee at any time and for almost any reason, and employees can also leave their jobs at any time. However, there are important exceptions, including anti-discrimination laws, employment contracts, and public policy protections that limit when termination is allowed.

Which States Follow At-Will Employment?

At-will employment is the default employment model in 49 out of 50 states in the U.S. Montana is the only state that does not follow at-will employment. In Montana(opens in a new tab), employers must have a valid reason for terminating an employee, and employees can only be fired for just cause. For all other states, employers and employees alike can, in most cases, terminate employment for any reason.

Exceptions to At-Will Employment

While at-will employment is the default model in most U.S. states, there are some exceptions to this rule. It’s important to note that not all of these exceptions are recognized by all jurisdictions. Make sure to do your due diligence and confirm if the exceptions are recognized in your state. The exceptions to at-will employment — detailed below — are based on federal and state laws, as well as public policy considerations.

Employment Contracts

One exception to at-will employment comes in the form of an explicit employment contract(opens in a new tab). In some cases, an employer and employee may enter into an employment contract that outlines the specific terms of their employment, including the reasons for which the employee can be terminated. In these cases, the at-will employment rule does not apply. Instead, the terms of the contract will dictate the employment relationship.

Implied Contract

Another exception to at-will employment is an implied contract(opens in a new tab). An implied contract is a verbal or written agreement between an employer and employee that is not explicitly stated via an employment contract. For example, if an employer promises job security to an employee in exchange for their loyalty and hard work, this could potentially be considered an implied contract. If an employer violates this implied contract by firing the employee without a valid reason, the employee might have grounds for a wrongful termination lawsuit.

Public Policy Considerations

Public policy(opens in a new tab) is another exception to at-will employment. In some states, employees are protected from being fired for reasons that violate public policy. This means that an employer cannot terminate an employee for reasons that are considered morally or ethically wrong by society. For example, an employer cannot fire an employee for reporting illegal activities within the company or for taking time off to serve jury duty. Now, each state’s public policies may differ, so keep in mind that interpretations of this exception can vary from state to state.

What States Are Not At-Will Employment?

As we mentioned earlier, Montana is the only state that doesn’t follow at-will employment. In Montana, employers must have a valid reason for terminating an employee, and employees can only be fired for just cause. But what is just cause?

Just Cause Definition 

In Montana, just cause(opens in a new tab) is defined as a reason that is job-related and is based on the employee's performance or conduct. This means that an employer must have a valid reason for firing an employee, like poor performance, misconduct, or violation of company policies.

Exceptions to Just Cause

There are some exceptions to the just cause rule(opens in a new tab) in Montana. These exceptions include:

  • Employees who are still in their probationary period

  • Employees who are employed on a temporary or seasonal basis

  • Employees who are employed on a project basis

  • Employees who are employed on a casual basis(opens in a new tab)

What Does This Mean for Employers and Employees?

For employers, understanding at-will employment laws is crucial to avoid potential legal issues. Employers should be aware of the exceptions that apply to at-will employment and ensure they have valid reasons for terminating an employee.

For employees, understanding at-will employment laws can help them better grasp their rights and protect themselves from wrongful termination. Employees should also be aware of the exceptions to at-will employment and know when they might have grounds for a wrongful termination lawsuit.

At-will employment is the default employment model in most states in the U.S., with the exception of Montana. Employers and employees should be aware of the state laws that govern at-will employment and understand the exceptions to this rule. By understanding at-will employment, both employers and employees can protect themselves and avoid potential legal issues.
