Answer:
employment-at-will policies
Step-by-step explanation:
Based on the information provided within the question it can be said that those statutes are referred to at employment-at-will policies. Like mentioned in the question this is a policy stating that a U.S employer may terminate the employment of an individual immediately without having a valid reason to do so. This is the case as long as it is not discovered that the employer fired the individual because of an illegal reason such as race, religion, gender, etc.
