As an employer or an employee, getting into an at-will agreement seems to be the best agreement to sign to, because here you will not only have the freedom to leave at any given time, but you also get to practice mobility, which is a great addition to your career growth and flexibility. There is no need for at-will employment lawyers because this is something that you agree between you and your employer and since there is no contract that ties any of you down, you do not need to file for anything when as the employee you decide to leave or the employer decides to terminate your services.
