Final answer:
For individuals, a professional standard is to give at least two weeks of notice when changing employment, but contractual obligations may dictate a different timeline. For employers with more than 100 employees, federal law requires a 60-day written notice before plant closings or mass layoffs.
Step-by-step explanation:
When discussing the requirements for notice of change in employment or change in business address, it is often relative to specific laws or company policies. For individuals, it’s a good professional practice to provide at least two weeks of notice when resigning from a position, but always check any contractual agreements you might have with your employer for specific terms you agreed to.
However, for employers, the situation can be quite specific, especially when it involves larger workforce changes. According to federal regulations, specifically the Worker Adjustment and Retraining Notification (WARN) Act, employers with more than 100 employees are required to provide written notice 60 days before implementing plant closings or mass layoffs. This significant lead time is mandated to ensure that employees have sufficient notice to prepare for the transition and seek other employment or training opportunities.
