It depends. There are some employees who are exempt from overtime. These workers are usually employed in an administrative, executive or professional capacity, and the Federal Regulations and courts have a number of guidelines as to whether an employee falls into one of these catagories. If you are not exempt, you should be compensated at 1 1/2 times your hourly rate for hours worked over 40 each week. The federal law covering overtime, the Fair Labor Standards Act, has a two year statute of limitations for non-willful violations of the act by the company, three years for willful violations. Again, courts have interpreted whether a company's actions are willful. I do not know from your post whether all of the time you worked was three or more years ago or if that is just when the practice started. If some of the time you worked was within two or three years, you may have a claim for overtime unless you were an exempt employee during that time period.
