A more thorough explanation:

A plant closing is when a company permanently or temporarily shuts down a single location or one or more parts of a location, which results in job loss or a significant reduction in work hours for at least 50 employees (excluding part-time employees). This is defined by the Worker Adjustment and Retraining Notification (WARN) Act.

Employers are required to give their workers 60 days' notice before a plant closing or mass layoff occurs.

A car manufacturing company decides to close one of its factories due to financial difficulties. The factory employs 200 workers, and the closure will result in the loss of jobs for 150 employees. This is considered a plant closing under the WARN Act, and the company must provide 60 days' notice to the affected workers.

Another example could be a retail store chain closing down one of its locations due to low sales. If the closure results in the loss of jobs or significant reduction in work hours for at least 50 employees, it would be considered a plant closing under the WARN Act.

These examples illustrate how a plant closing can affect a large number of employees and why it is important for employers to provide advance notice to their workers.
