At-Will Employment and Wrongful Termination:
Most employees in the U.S. work at-will, which means an employer can fire them at any time, for any legal reason. This can protect employers from wrongful termination. However, there are several common situations when an employee may not be considered at-will.
Obviously, you should never fire someone for illegal reasons, such as their race or gender. But to avoid being sued, it’s also important to document your reasons for terminating an employee so that you can prove it was not done for illegal reasons.
