I can assure you all the plants have 5S in some form. I can also say that a lot of tools and materials go missing. It got so bad at my plant, electricians and engineers would sometimes come to IT to borrow our tools. We had to put a stop to that once our tools started not coming back.Which does not address the point. Are you saying these UAW represented plants don't have 5S, and thus, their repetitive low skill jobs require more experience?
But if you're just making a statement, yes.
