A more thorough explanation:

Definition: No man's land refers to a situation where there is a lack of clear jurisdiction between a state government and the federal government over labor disputes. This term was commonly used in the 1950s, but its use has declined as later laws have clarified jurisdictional issues.

Example: Imagine a company that operates in multiple states. If there is a labor dispute between the company and its employees, it may not be clear which government has the authority to intervene and resolve the issue. This creates a no man's land situation where neither the state nor the federal government can take action.

Explanation: The example illustrates how a no man's land situation can arise in labor disputes. When there is no clear jurisdiction, it can be difficult to determine which government has the authority to intervene and resolve the issue. This can lead to delays in resolving the dispute and can create confusion for both the company and its employees.
