If you were paid for your work, even if the wages went to your parents because you were a minor, the employer owes you nothing in terms of pay--you were already paid. If you were injured while working, you may be able to sue for the injury, depending on whether the employer was at fault in causing it (e.g. faulty safety equipment or procedures; careless coworker) and how long ago it was (i.e. if the statute of limitations has not yet run out). To explore this option, consult with a personal injury attorney.
