What is the Fair Labor Standards Act?

The Fair Labor Standards Act is the federal law that says employees are entitled to be paid minimum wage and overtime equaling time-and-a-half the regular rate for every hour they work over 40. The law begins with presumption that everyone is entitled to overtime and carves out exemptions from that. If you do not fall with them on those exemptions your employers legally require to pay you time and a half for every hour you work over 40.
