Toyota, Nissan, and a lot of other manufacturing companies do not utilize union labor. I don't know if this is at all of their plants but at least the ones here. It costs too much to hire and train a workforce to have constant turnover. It is much cheaper to pay solid wages and great benefits. I won't claim that all companies believe this but it is true and most consistently successful companies take very good care of their employees because they are seen as an asset and not a liability.
Most manufacturing positions are not minimum wage, they usually start significantly higher and require more training and skills. Companies will pay what they need to in order to acquire and retain the talent they need. They will pay as little as they can but they will pay. They act in their best interest just like everyone else does.
