At-Will Employment
At-will employment means either the employer or the employee can terminate the working relationship at any time, for any reason that is not illegal (such as discrimination), and without advance notice, unless an employment contract, collective bargaining agreement or specific statute states otherwise.
At-will is the default rule in nearly every U.S. state (Montana is the notable exception after an initial probationary period). It does not override anti-discrimination law, whistleblower protections or the specific terms of an individual employment contract or offer letter — at-will status and contractual protections can coexist.
Most other developed economies do not follow the at-will model; many require notice periods, severance, or a demonstrated cause for termination by default, which is why the concept surprises candidates relocating internationally into U.S. roles.
