For almost 200 years during the Middle Ages, Christian Crusades wrested control of the Palestine region from the SelÃ§uk Turks due to a series of military incursions made up of Christian armies largely from Western Europe. The control that the Christian Crusades exerted over the Holy Land was tenuous at best.
Similarly if an employee is contracted to work 40 hours per week normal time, then any hours in excess of the 40 hours is overtime. Overtime is not compulsory and employees can refuse to work overtime on short notice, unless the employee contractually agreed to be available to work overtime on short notice. In circumstances we overtime work on short notice is required by the employer, fairness towards the employee must be taken into consideration.
Some employees are exempt from overtime, and therefore can be asked to work more then 40 hours a week without receiving overtime pay. Some overtime-exempt jobs are specified in federal overtime law, such as most white collar jobs, while other exemptions are specific to Florida's state overtime laws.
