Even the states that do not have meal and break provisions for adult workers commonly have provisions requiring that workers under age 18 receive more frequent or longer breaks than adult employees receive. 33 states, plus Guam, and Puerto Rico have separate laws for minors regarding meal breaks. Typically these laws are stricter and provide for more frequent and longer breaks than adults receive.
Your state labor department and/or the federal Department of Labor may also be able to provide you additional information and assistance. More information about youth and child labor may be found at the Department of Labor website.
