Florida Labor Law
448.01 Legal day's work; extra pay.--
(1) Ten hours of labor shall be a legal day's work, and when any person employed to perform manual labor of any kind by the day, week, month or year renders 10 hours of labor, he or she shall be considered to have performed a legal day's work, unless a written contract has been signed by the person so employed and the employer, requiring a less or greater number of hours of labor to be performed daily.
(2) Unless such written contract has been made, the person employed shall be entitled to extra pay for all work performed by the requirement of his or her employer in excess of 10 hours' labor daily.
448.05 Seats to be furnished for employees in stores; penalty.--If any merchant, storekeeper, employer of male or female clerks, salespeople, cash boys or cash girls, or other assistants, in mercantile or other business pursuits, requiring such employees to stand or walk during their active duties, neglect to furnish at his or her own cost or expense suitable chairs, stools or sliding seats attached to the counters or walls, for the use of such employees when not engaged in their active work, and not required to be on their feet in the proper performance of their several duties; or refuse to permit their said employees to make reasonable use of said seats during business hours, for purposes of necessary rest, and when such use will not interfere with humane or reasonable requirements of their employment, he or she shall be guilty of a misdemeanor of the second degree, punishable as provided in s. 775.082 or s. 775.083.
There was nothing I could find about breaks and lunches.
