Final answer:
An HR Professional's update to a Member's Active Status Program is reflected immediately, allowing the member to see changes in real-time without waiting for a period like 24 hours or until the next payroll cycle.
Step-by-step explanation:
When an HR Professional updates a Member's Active Status Program, the new status will be visible to the Member immediately. The immediacy of this update means that the member does not have to wait for a specific duration such as 24 hours or for the occurrence of an event, such as the next payroll cycle, to see the changes. It also implies that this update is not restricted to office hours; rather, it's a real-time change.
