Most employers are required to pay overtime to at least some of their employees. The overtime premium is half of your usual hourly rate. This means you are entitled to "time and a half" -- your usual hourly rate plus the 50% overtime premium -- for every overtime hour you work. Not all employees can earn overtime, however. Whether you are entitled to overtime pay depends on your state's law, your job duties, and how many hours you have worked.

The original purpose of this rule was to spread the work around and get as many people as possible off the unemployment
Many employers give employees a half hour or so to eat lunch, whether paid or unpaid. This common practice is not required everywhere, however: The federal wage and hour law, called the Fair Labor Standards Act (FLSA), doesn't require employers to provide meal or rest breaks. Some states have stepped into the breach to require such breaks, but others have not.
