Ohio does not have a law so the federal law applies. You can read it here: http://www.dol.gov/dol/topic/workhours/breaks.htmIt depends on whether the worker is an adult or a minor. If the worker is an adult, then there's no law that says that the company has to provide a lunch break, or any other sort of break. Minors get a half hour break for every five consecutive hours that they work.
