Final answer:
The timeframe for a pharmacist, intern, or pharmacy technician to notify their regulatory board of a change of address or employer is not universally defined in the provided information and can vary by state regulations.
Step-by-step explanation:
The question addresses the legal requirements for a pharmacist, intern, or pharmacy technician to notify their regulatory board when there is a change of address or employer. This question refers specifically to regulations that pharmacy professionals must follow, which can vary by state. The provided information regarding employers with more than 100 employees providing written notice 60 days before plant closings or large layoffs is related to labor law but does not directly answer the question about the notification requirements for pharmacy professionals. It is essential to provide proper notice when changing employers; for many professions, a standard two weeks notice is customary. However, pharmacy professionals should check with their state board to find the specific timeframe required for notification, as it can vary.
