A more thorough explanation:

Definition: At will means subject to one's discretion, as one wishes or chooses. This term is often used in legal relationships, where it means that the relationship can be terminated or discharged by either party without cause. For example, employment at will means that an employer can terminate an employee at any time, for any reason, or for no reason at all.

Examples:

• My apartment lease is at will, which means I can move out whenever I want without penalty.
• The company's policy is to hire employees at will, so they can terminate them if they're not a good fit.
• As a freelancer, I work on projects at will, choosing which ones to take on and when to complete them.

These examples illustrate how the term at will can be used in different contexts to describe a relationship that is subject to one's discretion. In each case, the parties involved have the freedom to make choices and end the relationship without cause.
