A more thorough explanation:

The lunch-hour rule is a legal principle that states that an employer is not liable for any injuries caused by or to an employee during their lunch break, as long as the employee is not performing any work-related tasks and is off the employer's premises.

For example, if an employee goes out for lunch and gets into a car accident on the way to the restaurant, the employer would not be responsible for any injuries or damages. However, if the employee was running an errand for the employer during their lunch break and got into an accident, the employer could be held liable.

The lunch-hour rule is in place to protect employers from being held responsible for accidents or injuries that occur outside of the workplace and outside of work-related activities. It also encourages employees to take breaks and enjoy their lunch without fear of being held responsible for any accidents that may occur.
