What organization established the employment at will clause in employment contracts? How does this clause work legally? Are law cases regarding the clause frequent? If an employee is fired for a debatable issue is the attempt of the fired employee to dispute the fire ignored because of the employment at will clause? If there is a point system within the place of employment, does that supersede the employment at will clause, or does it typically depend on the specific contact and it's provisions and ramifications therein for which takes precedence?
