I worked appox 20 hrs overtime this pass week and didn't received overtime pay. My understanding. Is cause im not entitled toit

You should contact an employment attorney. It's entirely possible that you are entitled to the overtime pay, but your employer is refusing to pay you. If your employer is not paying you overtime in the past, you may be entitled to unpaid overtime wages, additional money as a penalty, and attorney's fees. My firm handles these cases. We work on a contingency fee and provide free consultations   Ohio unpaid overtime attorney www.mcoffmanlegal.com
