Which employment doctrine allows employees to quit employment at any time without cause and without providing a reason?

The concept of at-will employment is a fundamental principle in many employment relationships, particularly in the United States. This doctrine allows either the employer or the employee to terminate the employment relationship at any time, for any lawful reason, or for no reason at all. This means that employees have the freedom to leave their jobs without having to explain their decisions or provide justifications, promoting flexibility in the employment landscape.

On the other hand, the right to work laws generally pertain to union membership and do not specifically address the nature of employment termination. Just cause employment signifies that an employee can only be terminated for specific reasons or behaviors, often outlined in a company policy or employment contract. Contractual employment involves a binding agreement that typically defines the terms of employment, and might require an employee to provide notice or reasons for leaving.

Therefore, at-will employment stands out as it encapsulates the idea of unrestricted employee rights to resign without cause, which aligns with the question's focus on the freedom to quit employment at any time without providing a reason.
