Contact your state Department of Labor to file a wage complaint. Non-payment or late payment of wages are something the DOL does not have any patience with. As in once you file a complaint showing the hours worked and that you weren't paid, they will give your employer the option of paying you immediately or being shutdown and locked out until all back wages are paid. Additionally, any adverse action against you by your company (extortion, termination, coercion, etc) after that complaint is something the DOL takes about as well as a defendant flipping off a judge in court. Largely this is because employee wages have first claim on a company's assets when settling liabilities. If the DOL has to force your employer into bankruptcy to pay wages immediately, tough shit for your employer. Which gives your employer a very strong incentive to cooperate promptly.
