I've learned that inside today's manufacturing plants, your comment is not welcome until asked for. There are all kinds of grants, cost offsets, tax credits, et al, over what equipment you buy, who you hire, what training you provide, and so on...............

Being smart or correct is not a valuable commodity in a plant. Being safe and approachable seems to be what they want. I just keep stuff running electrically.
