In general, your analysis is correct that the state of Florida does not limit the amount of hours worked in salaried positions. One point that should be considered is the definition of a truly managerial position for purposes of possible overtime. The only other restrictions of hours is in certain positions where safety could be an issue such as truck drivers.
The question would be whether or not you are truly a salaried employee. If u should be getting paid hourly you would be owed overtime for many of these hours. For an analysis of this issue check ou my employee rights blog at www.takethisjobnshoveitblog.com
