Circa that time, GM and Ford were going to Japan to study the "Toyota Production System" now more generically known as Lean Engineering & Manufacturing. Anyone working at NUMMI knew about that because of Toyota. "Hey, go 5-S your work place" was common.
Around that time, GM asked Toyota, "Where did you learn this"
Toyota's response was "Are you kidding, I learn from you guys (Ford, GM)"
Toyota believes in providing wages good enough that the employees don't need a union.
I guess there is a silver lining to union leaders getting jail time for corruption.
Does UAW have better wages?
The good thing about UAW is that it does put pressure on the companies for higher wages, but those companies can just pay those wages without the middle man of the union and its a win for both the employee and the company.
