I work at a medium sized manufacturing plastics plant. We have had to add robots because we can't find competent people to run our presses. We can find them but they can't count or speak English or they work until their first paycheck and they quit. The amount of money we spent on robots was very easily made back in a short period of time. It's sad but we have to do what we have to do to stay competitive.
