this is close to just straight up misinformation, but I'll point out the fundamental difference that you are ignoring in your analogy. You pay your union rep (via dues). It's not that you work for your union rep, it's that they work for you, just like you work for your company.

Also, aren't unions in the U.S. democratic in the sense that the union members elect their reps? AFAIK you don't vote for company management, so that's another power differential.
