Quote from TGregg:
Absolutely. You should invest thinking that unions are not important. Ignore them, their workers barely make the minimum wage (if that). You'll clearly get what you deserve.
Edit: OK, maybe you don't really know about the UAW, so let me fill you in. I've been on the line in different plants in metro Detroit - not working the line but doing various things around it. First off, it is a harsh, regimented society where power comes primarily from how many years you've been on the job. How good a job you do is completely irrelevant. That's trouble #1.
Trouble #2 is jobs are protected. Long story short, I was involved in one example of unions protecting jobs where tech could deliver cheaper, better, faster solutions.
Trouble #3 is pensions and insurance. Reasonable investors already know all about this trouble.
