Final answer:
The information provided pertains to employer notice requirements for plant closings or layoffs, not LTC facility rate changes. LTC facility rate increase notice requirements differ by state regulations.
Step-by-step explanation:
The question refers to the required notice period for an increase in rates at a Long-Term Care (LTC) facility. While the provided information discusses a 60-day notice requirement for employers with more than 100 employees in cases of plant closings or large layoffs, this does not directly apply to LTC facilities and their rate increases.
Requirements for LTC facility rate increases can vary by state and are typically governed by state regulations, rather than federal laws like the WARN Act, which mandates the 60-day notice for large employers. However, it's common for LTC facilities to provide a similar timeframe for rate increases to ensure residents and families are duly notified and can make appropriate arrangements.
