Federal wage and hour law does not require rest or meal periods, except for nursing mothers, but it does set standards for when work breaks, including meal periods, rest periods, and sleeping time, must be counted as paid work time. Whether breaks are required is left up to the states. Ohio has provisions requiring meal or rest breaks for minors.
U.S. Department of Labor Wage and Hour Division regulations do specify when work breaks including meal periods, rest periods, and sleeping time that, if provided, must be counted as work time subject to federal minimum wage and overtime requirements (29 CFR 785.18 through 785.23).
Railroads. A company operating a railroad over 30 miles in length or an interurban railroad or street railway over 4 miles in length must provide a conductor, engineer, fireman, brakeman, or trainman on a train; a telegraph operator; or a conductor or motorman on a street railway who has worked for 15 consecutive hours at least 8 hours of rest before returning to duty. There is an exception in cases of detention of trains or cars caused by an accident. These companies must regulate the hours of employment of their employees so that each employee has at least 8 consecutive hours of rest in each 24-hour period (OH Rev. Code Sec. 4973.11).
