When are employees NOT entitled to the 4-hour minimum pay?

The reasoning behind the correct answer centers on the entitlement to the 4-hour minimum pay being a protection for employees when they report for work under normal circumstances. When employees are ordered back after a meal, they are generally expected to continue their work obligations, which means their compensation can follow the standard pay structure based on their actual hours worked, rather than triggering the minimum pay guarantee.

Conversely, in situations where weather is clear, employees might still be entitled to minimum pay based on other factors not specified in the question. If an employee refuses to report for duty, that would likely negate their entitlement as they are not fulfilling their work responsibilities. Lastly, when employees are sent home early, they typically maintain their right to the minimum pay, as they showed up for their scheduled shifts. Therefore, being ordered back after a meal signifies a continuation of expected duties, making it the situation where the entitlement to the 4-hour minimum pay does not apply.
