Yes, if you are a minor. Florida law requires that minors work no more than four consecutive hours without a 30-minute uninterrupted break.  See Chapter 450, Part I, Fla. Stat., generally.  Once an employee reaches 18 years of age, neither state nor federal law makes provisions for breaks except in certain regulated occupations, like commercial truck drivers. Breaks for adults are at the discretion of the employer and are usually established through company policy.
