As an employee, you expect to be paid fairly based on a variety of state and federal laws. For example, each state has a minimum wage that companies must pay all employees.
Although there are some exceptions to the minimum wage laws, unless you are one of the exceptions, your employer is legally obligated to pay you at least the federal minimum wage or the minimum wage that is mandated by a state. This amount is determined by whichever wage amount is higher. If you qualify for minimum wage, but find that your employer is paying you less than the legally-mandated amount, by law you can file a lawsuit or make a wage claim against your employer.
