While there are no national on-call scheduling laws, your restaurant may be subject to regional regulations. To find out which laws — if any - apply to your business, simply search for “[your city and/or state]” + “on-call scheduling” laws on Google. Doing so will yield resources that speak to your specific area's laws. You should also consult with your local authority and/or legal counsel to ensure you're getting the most up-to-date information on on-call scheduling.
