Answer:
C. Federal and state legislation does not interfere with an employer’s right to discharge.
Step-by-step explanation:
At-will employments involves contractual arrangement whereby both parties are aware of it. Hence, option A is wrong
A person can be fire for "no reason at all" under At-will employment. Hence option B is wrong
The U.S. Supreme Court has not found the "at-will" rule to be unconstitutional, not even recently. Hence, option D is wrong as well.
However, Federal and state legislation does not interfere with an employer’s right to discharge. Hence, option C is the correct answer.
