A more thorough explanation:

Definition: Joint action refers to a group of people working together to achieve a common goal or objective. It can also refer to a legal proceeding taken by two or more parties together.

Example: A group of friends organizing a charity event is an example of joint action. They are working together to raise funds for a cause they all support. Another example is a joint lawsuit filed by two or more individuals against a common defendant.

These examples illustrate how joint action involves collaboration and cooperation among individuals or parties to achieve a shared objective or outcome.
