A minimum wage is the absolute minimum amount of money that someone can be paid for a specified job. It was created to ensure that no one is unfairly compensated for their work. As of July 2009, the federal minimum wage is $7.25 per hour.

In the U.S., the minimum wage is regulated by the federal agency called the Department of Labor, but states have the flexibility to set their own higher (or in special cases, lower) minimum wage. There are also exceptions to who must receive the minimum wage. Waiters and other workers who regularly receive tips have a much lower minimum wage ($2.13/ hour). And sometimes employers can pay workers who are under 20 only $4.25 per hour for their first 90 days on the job.
